Corentin Wallez c0810e7e6e Fix gn check in Chromium
- Move headers from libtint_sem_src into libtint_core_all_src so that
there is no circular header dependency between headers of these two
targets. libtint_sem_src is now just a hack to have a different name for
a few .cc files.
 - Made libtint_core_src publicly depend on its deps so that headers of
libtint_core_all_src are made visible through it.
 - Added spvtools dependencies in a couple places that were mistakenly
removed in a previous commit.
 - Moved helpers common to multiple unittest targets out of
tint_unittests_core_src and into a tint_test_helpers target that
all tint_unittests_source_set depend on.
 - Ran GN format that reordered some lists a bit.

Antonio Maiorano 3244bcdb67 Rename sem_*.cc to *.cc
This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.

Ben Clayton 1773535e1c Resolver: Validate <storage> var types
https://gpuweb.github.io/gpuweb/wgsl/#variable-declaration
Variables in the storage storage class and variables with a storage
texture type must have an access attribute applied to the store type.

https://gpuweb.github.io/gpuweb/wgsl/#module-scope-variables
A variable in the storage storage class is a storage buffer variable. Its
store type must be a host-shareable structure type with block attribute,
satisfying the storage class constraints.

Fixup tests, including those that were producing warnings about `var <in>`

The WGSL writer seems to want to put a newline after every decoration block, leading to some ugly output. I'll fix this as a separate change.

Arman Uguray d13982ff2e [msl-writer] Support MSL compiler validation in unit tests
The MSL writer GTest harness (TestHelper) now provides a function to
invoke the XCode SDK Metal compiler for the MSL output of a given
tint::Program.

The tint_unittests binary now provides the `--validate-msl` and
`--xcrun-path` command-line flags to optionally enable MSL validation
and to configure its path.

The MSL validation logic itself is conditionally compiled based on the
TINT_BUILD_MSL_WRITER define. The TINT_BUILD_* flags were previously
not propagated to the GTest binary which this CL addresses by linking
the common/public tint configs when building the tint_unittests_main
target.

Ben Clayton 1b8d9f227b CloneContext: Don't create named symbols from unnamed
Registering a new Symbol with the NameFor() of the source symbol creates

Update CloneContext::Clone(Symbol) to properly clone unnamed symbols.

Update (most) the transforms to ctx.Clone() the symbols instead of
registering the names directly.

Fix up the tests where the symbol IDs have changed.

Note: We can still have symbol collisions if a program is authored with
identifiers like 'tint_symbol_3'. This will be fixed up in a later
change.

- Structs used as entry point parameters and return values cannot have
  runtime array or nested struct members
- Multiple pipeline IO attributes on a parameter, return type, or
  struct member is not allowed
- Any given builtin and location attribute can only appear once for
  the return type, and across all parameters

Removed tests for nested structs from the SPIR-V transform/backend.

Ben Clayton 91da97d6c3 Remove ast::NullLiteral
This isn't in the WGSL spec, nor is it generated by readers.
This was only used inside the SPIR-V writer, but this remaining usage was removed in the parent change.

Ben Clayton eae161cd9f writer/spirv: Clean up constant generation
Requiring a temporary stack-allocated ast::Literal is an unpleasant requirement to generate a SPIR-V constant value.
GenerateU32Literal() was also creating an invalid AST - the type was U32, yet an an ast::SintLiteral was used.

Instead add Constant for holding a constant value, and use this as the map key.

This also removes the last remaining use of ast::NullLiteral, which will be removed in the next change.

Antonio Maiorano 03c01b5266 Move function validation from Validator to Resolver
* Fixed many tests that now failed validation. Most of the time,
functions declared that they returned a type, but with no return
statement.
* ProgramBuilder::WrapInFunction now returns the function is creates,
and std::moves its StatementList.
* ProgramBuilder: Added Return function to create ast::ReturnStatements
more easily.
