dan sinclair f374b819d9 Remove `sig` deprecation.
This CL removes support for the `sig` member in `frexp`. It is now an
error if `sig` is used, the deprecation is removed.
`fract` should be used instead.

James Price 61feebef38 tint/tests: Actually validate the generated WGSL
We weren't actually enabling WGSL validating in Tint in the E2E test
runner.

Mark a few tests as SKIP for cases that do not actually validate.

dan sinclair 7092786f31 Fixup return of HLSL sign to match WGSL.
The HLSL `sign` method returns an `int` result (scalar or vector). The
WGSL `sign` expects the result to be the same type as the argument. This
CL injects a cast to the correct type after the `sign` call in the HLSL
generated source.

Ben Clayton f3f813eb0c tint: fix const eval short-circuiting with mixed runtime and constant expressions
For logical binary expressions that can be short-circuited, if the rhs
tree contained a mix of constant and runtime expressions, we would
erroneously mark the node as runtime, although some of its children were
resolved as kNotEvaluated. This would then fail during backend
generation.

This is a fork of 115820, addressing review comments, as amaiorano is OOO this week.

James Price 744d0eb4aa tint: Use "demote-to-helper" semantics for discard
Discard statements no longer affect the behavior or uniformity
analysis. Update the resolver, validator, and several tests to reflect
this.

Some E2E tests were removed as they had loops that are now considered
to be infinite.

Use the DemoteToHelper transform to emulate the correct semantics on
platforms where discard is (or may) terminate the invocation in a
manner that would affect derivative operations.

We no longer need the UnwindDiscardFunctions transform for HLSL, which
already implements the correct semantics. However, we still run the
DemoteToHelper transform for the HLSL backend due to issues with FXC's
handling of discard statements (see crbug.com/tint/1118).

Ben Clayton 22c4850b06 tint/resolver: Allow array sizes to be unnamed override-expressions
I got the rules around this wrong. This should be allowed, but the array types cannot compare equal if they are unnamed override-expressions.

Fixed tint:1737

Ben Clayton a92f4259d5 tint/writer/msl: Move packed_vector hacks to transform
Attempting to paper over all the MSL standard library holes for packed_vector in the MSL writer added complexity to the writer, produced messy output, and didn't actually catch all the cases where casts were needed.

Add a new PackedVec3 transform that applies the packed_vector -> vec casts in a smarter, more precise way.

To match the spec.

Also add a bunch of missing texture test cases to

broken because these were not being exercised.

dan sinclair b3b027d3cd Update lexer to not include `-` in numbers.
This CL removes the parsing of a `-` in front of numerics when lexed.
This will cause the number to become a UnaryOperator negation then the
number instead of a negative number.

This CL fix the spv code generated for atomicCompareExchangeWeak,
specifically the emulated `exchanged` field of the returned struct.
It should be true if and only if the `old_value`, i.e. the return value
of spv `OpAtomicCompareExchange`, equals to the comparator, rather than
equals to new value.
