James Price dfc1a2c081 Remove support for the @stride attribute
We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.

The WGSL parser no longer has to handle attributes on types.

James Price 8bcecf365d Remove @block attribute
Since this was the only attribute allowed on structures, we can also
remove the parsing code for them. However, we still need to have
attributes on the struct AST node, since the AddSpirvBlockAttribute
transform adds one.

James Price d0ec88ce61 Add support for override keyword and @id attribute
This replaces the @override keyword that was previously used for
pipeline-overridable constants.

Support for pipeline-overridable constants in Dawn is hidden behind
the "disallow-unsafe-APIs" toggle, so we can make this change directly
instead of deprecating and continuing to support the old syntax.

Austin Eng 2f218e2b21 Implement upstream RequestDevice, add native-only CreateDevice
This CL implements RequestDevice and also has changes for
Dawn to internally use wgpu::FeatureName enums, instead of
strings. Some of the string handling is kept for now to
support the deprecated creation path. GetFeatureInfo is added
to the instance to get a name and description of the feature,
for reporting in about://gpu.

Dawn device toggles are now passed in an extension struct off
of the device descriptor. This is only supported in dawn_native,
and not dawn_wire, for now, since dawn_wire doesn't have a way
to serialize lists of null-terminated const char*.

To enable the client to check whether the toggle descriptor is
supported, a `dawn-native` feature is added which is supported
all the time with dawn_native, but not supported with dawn_wire.

Feature `dawn-native` also enables a synchronous version of
CreateDevice for convenience.

Jiawei Shao 1f25ea94bb dawn_wire: Directly use the data in deserialized buffer when possible
This patch tries to use the data directly in deserialized buffer
when the data is "data-only" and doesn't affect the control flow instead
of allocating and copying into a temporary buffer. Due to the protection
of TOCTOU attacks, currently we only set "wire_is_data_only" on the
parameter "data" in Queue.WriteBuffer() and Queue.WriteTexture().

With this patch, the performance of dawn_perf_tests
BufferUploadPerf.Run/*_WriteBuffer_BufferSize_* with "-w" will
be greatly improved (~20%) when the upload buffer size is greater than
1MB.

Ben Clayton ea3eee9885 resolver: Migrate validation to behavior analysis
Migrate some of the validation logic over to use the results of behavior
analysis.

The most significant changes are:
* Unreachable-statements now consider merge-points of control flow. For
  example, if all branches of a if-statement or switch-statement either
  return or discard, the next statement will be considered unreachable.
* Unreachable statements are no longer an error, but a warning. See
  https://github.com/gpuweb/gpuweb/issues/2378.
* Statements that follow a loops that does not break, or have a
  conditional will now be considered unreachable.
* Unreachable statements produced by the SPIR-V reader are now removed
  using the new RemoveUnreachableStatements transform.

Some other new changes include additional validation for the continuing
block for for-loops, to match the rules of a loop continuing block.
The new cases this validation is testing for are not expressible in
WGSL, but some transforms may produce complex continuing statements that
might violate these rules. All the writers are able to decay these
complex for-loop continuing statements to regular loops.

Ben Clayton bf39c8fb19 sem: Replace SwitchCaseBlockStatement with CaseStatement
The SwitchCaseBlockStatement was bound to the BlockStatement of an ast::CaseStatement, but we had nothing that mapped to the actual ast::CaseStatement.
sem::CaseStatement replaces sem::SwitchCaseBlockStatement, and has a Block() accessor, providing a superset of the old behavior.

With this, we can now easily validate the `fallthrough` rules directly, instead of scanning the switch case. This keeps the validation more tigtly coupled to the ast / sem nodes.

James Price 4cc4315d6c Allow array size to be a module-scope constant
Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.

The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.

Austin Eng 0eff5987f0 Add chained DawnTextureInternalUsageDescriptor
This chained struct can be used for internally adding usages to
Dawn textures. It will affect how the texture is allocated, but
not affect frontend validation.

One use case for this is so that Chromium can use an internal
copyTextureToTexture command to implement copies from a WebGPU
texture-backed canvas to other Web platform primitives when the
swapchain texture was not explicitly created with CopySrc usage
in Javascript.

Usage:

wgpu::DawnTextureInternalUsageDescriptor internalDesc = {};
internalDesc.internalUsage = wgpu::TextureUsage::CopySrc;

wgpu::TextureDescriptor desc = {};
// set properties of desc.
desc.nextInChain = &internalDesc;

device.createTexture(&desc);

Ben Clayton 6e459fecb7 sem: Add CompoundStatement
This change introduces sem::CompoundStatement, a new base class for
statements that can hold other statements.

sem::BlockStatements now derives from sem::CompoundStatement, and
this change introduces the following new CompoundStatements:
* `sem::IfStatement`
* `sem::ElseStatement`
* `sem::ForLoopStatement`
* `sem::LoopStatement`
* `sem::SwitchStatement`.
These new CompoundStatements are now inserted into the semantic
tree as now documented in `docs/compound_statements.md`.

The `sem::BlockStatement::FindFirstParent()` methods have been
moved down to `sem::Statement`.

The `Resolver::BlockScope()` method has been replaced with
`Resolver::Scope()` which now maintains the `current_statement_`,
`current_compound_statement_ ` and `current_block_`. This
simplifies statement nesting.

The most significant change in behavior is that statements now
always have a parent, so calling Block() on the initializer or
continuing of a for-loop statement will now return the
BlockStatement that holds the for-loop. Before this would
return nullptr.

Ben Clayton 93e8f527ee wgsl: Deprecate [[access]] decorations
Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.

The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
   var x : [[access(x)]] alias_to_struct;

Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.

Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.
