Stephen White 7cf3b28a87 GLSL writer: validate all entry points with glslang.
Generate and validate all entry points individually.
This is required since GLSL has separate shader files, and
can only have a single "main" entry point.

Stephen White a9f8c7db81 Implement GLSL writer backend.
This is a modified version of the HLSL writer.
Basic types, arrays, entry points, reserved keywords, uniforms,
builtin uniforms, structs, some builtin functions, zero initialization
are implemented. Textures, SSBOs and storage textures in particular are
unimplemented. All the unit tests "pass", but the output is not correct
in many cases.

triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.

James Price af89c729ed writer: Move sanitizers into the backends
Adds a new single-function API for the generators, which applies the
sanitizing transform and performs the generation in one step, and
returns a result object which contains the generated code and success
status/diagnostics.

The new APIs take an `Option` structure to control backend-specific
generation details (e.g. MSL fixed sample mask). The result objects
also provide backend-specific feedback (e.g. whether a UBO of buffer
lengths was generated).

HLSL needs a list of entry points to validate, and it's the HLSL
sanitizer that generates an entry point for programs that do not have
one. This change makes the HLSL generator return the list of
post-sanitize entry points so that the Tint executable can forward
them to the validation code.

Ben Clayton eb496d0a4d transform: API cleanup
Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.

Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.

Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Ben Clayton 6b4924fb0e Add TINT_UNREACHABLE() and TINT_ICE() helper macros
Appends an error message with the tint compiler source location to the
provided diagnositic list, and then calls the global error handler if
one is set.
Tests and the sample app now register an error handler to print the
diagnostic list to stderr and abort when NDEBUG is not defined.

All uses of assert(false) have been fixed up to use these macros.

Also demangle - this also reduces a bunch of copy-pasta code.

Ben Clayton 844217fa34 Add Diagnostics to Program, reader::[wgsl,spirv]::Parse()
By putting diagnostics into the program, we can hold all the diagnostic messages for parsing and type determination in one place.
This also means that we can simplify the public WGSL and SPIR-V Parser interfaces to a single function.

Ben Clayton a6b9a8eb2f Split Program into Program and ProgramBuilder
Program is now immutable*, and remains part of the public Tint
interface.

ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.

Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().

Mutable ProgramBuilders can be moved into immutable Programs.

* - mostly immutable. It still has a move constructor and move
  assignment operator - required for practical usage - and the
  semantic information on AST nodes is still mutable.

Ben Clayton c40f627bea Migrate from using ast::Module to Program
Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.

As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.

As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.

Depends on https://dawn-review.googlesource.com/c/dawn/+/38522

Carl Woffenden 90c266de5a Removed Clang-specific pragmas to build with VS2019
When building for Windows with VS2019 (using 'is_clang=false') with the
default "warnings as errors" this occurs multiple times, halting the
build:

../../third_party/tint/samples/main.cc(88): error C2220:
the following warning is treated as an error

../../third_party/tint/samples/main.cc(88): warning C4068:
unknown pragma 'clang'

Since there's no shared macro for marking potential unused params the
simplest route of a (void) cast is chosen.

dan sinclair 987376cd21 Revert the namer changes.
This CL reverts the changes to use the top level namer in the various
backends. This is causing issues when rolling into Dawn in the case
where the tint generator is used to create SPIR-V which is sent to
SPIRV-Cross but then generator and inspector aren't used. The entry
points end up being incorrect as SPIRV-Cross gets the renamed entry
points.
