Validation of the input

[kvark]

Unlike GLSL and SPIR-V, for WGSL there is no other validator people could use. So it would be nice to be able to validate the sources completely, as an option that would presumably be enabled in debug mode by the user. Similar feature is already there in GLSL.

@kvark I think we can close this since the validator now is frontend agnostic

To clarify, when filing this issue we knew we'd be validating everything in the IR. The question about input validation is separate though, and it still stands. I.e. should the GLSL frontend have extra logic to detect if the incoming GLSL is valid to start with? Previously, @pjoe expressed interest in providing this logic.

Since WGSL is covered, I'm removing the "lang: WGSL" label. Please correct if I've misunderstood.

I think we can close this, we have IR validation and also front-end specific validation for things not present in the IR.
