* [hlsl-out] test mat2x4 to make sure our matCx2 code behaves properly
Require at least version 0.7.1 of ron, this version changed how floating points are
serialized by forcing them to always have the decimal part, this makes it backwards
incompatible with our tests because we do a syntatic diff and not a semantic one.
GLSL allows the last case of a switch statement to not have a `break`
statement causing it to be marked as fall-trough, naga's IR on the other
hand doesn't allow the last case to be fall-trough, this is fixed by
force marking it in the glsl frontend as not fall-trough.
GLSL also allows empty switch statements and without default cases,
naga's IR requires there be a default case, this is fixed by adding an
empty default case in the glsl frontend if no default case was present
in the switch statement.
Glsl defines two overloads for smoothstep that accept `min` and `max` as
scalars and the value as a vector, naga's IR is stricter and only allows
operators with the same dimensions, so this inputs must be splatted.
Introduce a new `TypeFlags::CONSTRUCTIBLE` flag, corresponding to
WGSL's "constructible types". Set this on the appropriate types.
Check for this flag on function return types.
The previous check compared rows to rows and columns to columns but
multiplication of matrices only needs the columns of the left matrix to
be equal to the rows of the right matrix.
* glsl-out: Implement bounds checks for `ImageLoad`
* Enable image bounds check snapshot tests for GLSL.
In addition to the snapshot.rs changes, this entails adding an entry
point function to `bounds-check-image-restrict.wgsl` and
`bounds-check-image-rzsw.wgsl`, including appropriate data in the
param.ron files.
* Apply comments

The new `check_one_validation` macro permits the source code to be a
computed expression, not just a string literal. This also cleans up
some of the handling of the optional guard expression.
