When indexing into vectors in a loop, FXC sometimes fails to determine
the max number of iterations when attempting to unroll the loop,
resulting in "error X3511: forced to unroll loop, but unrolling
failed.". We work around this by calling a function that sets the input
value at the input index into an inout vector. This seems to nudge FXC
enough for it to determine the number of loop iterations to unroll.

binding points to the corresponding index into the array of buffer
lengths. The transform reports whether it generated the uniform
buffers or not.
Use this transform from the MSL sanitizer, using the binding number as
the index into the array. This matches the behavior of spirv-cross,

After implementing validation and fairly exhaustive tests, discovered
that conversion of scalar vector to bool vector did not work in the
spir-v backend. For module scope variables, we use and rely on the
FoldConstants transform to ensure no conversion needs to take place.
This is necessary because we cannot easily introduce temporary values
and refer to them when casting at module scope. Note that for the same
reason, module-level conversions are always constant foldable, so this
works. For function-level conversions, implemented support to emit a
comparison against a zero value, and store the result in the bool
vector.

This pointer may pass through function scoped let statements.
To make this intrinsic easier to generate, inline the pointer lets and
remove chains of &*&*.

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.

Add a config parameter for the CanonicalizeEntryPoint transform that
selects between emitting builtins as parameters (for MSL) or struct
members (for HLSL).
This fixes all of the shader IO issues in Tint's E2E tests for MSL.
