dan sinclair 3abad2c125 When emitting a MSL struct initializer emit the struct name.
This CL changes the MSL emission for struct initializers to emit the
struct name first.

`const a = {.f=float3(1)}` becomes `const a = Normals{.f=float3(1)}`.

This fixes an issues where the initialization happens inside an array
which the downstream compiler rejected without the explicit struct
naming.

Antonio Maiorano a58d8c9fac tint: fix builtin calls and binary ops with abstract args of different type
If a call to atan2 with args of type AFloat and AInt is made, Resolver
would correctly select the atan2(AFloat, AFloat) overload, but if the
input args were of type (AFloat, AInt), it would attempt to constant
evaluate without first converting the AInt arg to AFloat. The same would
occur for a binary operation, say AFloat + AInt. Before constant
evaluating, the Resolver now converts AInt to AFloat if necessary.

This will be needed by an upcoming CL that fixes call statements to
builtins that return a constant value. Without this transform, the
constant value reaches the backend, where we don't currently deal with
abstract numbers. Note that the other backends (HLSL, MSL, GLSL) already
use this transform.

dan sinclair 4abf28e29b tint: Add basic support for chromium_experimental_push_constant.
This extension adds support for the push_constant storage class such
that it can be tested with WGSL test files. The real goal is to allow
future transforms that will add push constants that the SPIRV writer
will output.

The extension:

 - Adds the `chromium_experimental_push_constant` enable.
 - Allows the push_constant storage class for global variables.
 - Adds validation that the types are host-shareable for push_constant
   variables, and that they don't contain f16 (must be 32bit types
   only).
 - Validates that at most one push_constant variable is statically used
   per entry-point.
 - Skips validation that the extension has been enabled if
   kIgnoreStorageClass is used.

Tests are added:

 - For parsing of var<push_constant>
   - Caught a missing conversion.
 - For each of the validation rules.
 - For the wrapping of push constants in structs if needed by
   AddSpirvBlockAttribute.
 - For the layout and type rules of the storage class.
 - For a shader with multiple entry-points using various push constants.
    - Caught a missing reset of the previous push constant variable in
      the validation check that at most one is used.
    - Caught the missing wrapping in structs that had to be added to
      AddSpirvBlockAttribute.
    - Caught incorrect logic when adding diagnostics about the call
      graph leading to the reference to push constants.

types as follow:
WGSL type   -> GLSL type

David Neto 760c399cfb Delete tests with invalid SPIR-V inputs
The structured CFG rule was revised/clarified in SPIR-V 1.6 Rev2
Validation now rejects a few cases.

SpvParserTest, ValueFromBlockNotInBlockOrder
SpvParserFunctionVarTest, EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
SpvParserFunctionVarTest_EmitStatement_Phi_ValueFromBlockNotInBlockOrderIgnored
  - Originally from crbug.com/tint/804
    Invalid by SPIR-V 1.6 Rev2 update to validation rules:
     - Block 80 is a structurally reachable continue target
     - Block 25 is not structually reachable, and not part of the loop,
       but branches to 80.

vk-gl-cts/graphicsfuzz/cov-dead-branch-func-return-arg/0-opt.*
  -  The continue construct with the continue target 37[%37]
     is not structurally post dominated by the back-edge block 64[%64]
  - The SPIRV-Tools inliner no longer creates such cases.  It splits the
    single-block loop and pushes the continue target down.

vk-gl-cts/graphicsfuzz/nested-for-loops-with-return/0-opt.spvasm
  - The loop headed at block 46 does not structurally dominate its merge
    block 44.  There is a continue-target edge from 41 to 44.

SpvParserCFGTest_ClassifyCFGEdges_BackEdge_MultiBlockLoop_MultiBlockContinueConstruct_ContinueIsHeader.spvasm
SpvParserCFGTest_EmitBody_Loop_MultiBlockContinueIsEntireLoop.spvasm

SpvParserCFGTest, EmitBody_Loop_MultiBlockContinueIsEntireLoop
SpvParserCFGTest, LabelControlFlowConstructs_MultiBlockLoop_HeaderIsContinue
SpvParserCFGTest, SiblingLoopConstruct_ContinueIsWholeMultiBlockLoop
 - Continue target 20 also its own loop header, but is not structurally
   post-dominated by the backedge block.
 - Delete the end-to-end test.
 - Keep the unit test because it's about classifying edges, but disable dumping
   into the end2end suites.

Ben Clayton f47887d207 tint/writer/msl: Generate an array<T,N> helper
And remove the WrapArraysInStructs transform.

Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.

MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of
templated code.

This produces significantly cleaner output.
