dan sinclair 1d2ad81eb9 Update WGSL grammar builtins to match spec.
This CL removes the builtin_decoration from the parser in favour of
using IDENT tokens for builtins. We still convert to an enum in the
parser and validate the value provided.

dan sinclair 5370390096 Remove NOP.
The NOP command was added for complete SPIR-V bijectivity which is no
longer a goal of WGSL. The NOP command has been removed from the spec,
so remove from Tint.

in public_deps doesn't resolve the linking issue.

David Neto a92c114c1a [spirv-reader] Label control flow constructs
Label basic blocks with:
- their nearest enclosing structured control flow constructs.
- their nearest enclosing continue construct, if any
- their nearest enclosing loop construct, if any

A construct consists of a span of blocks in the computed block order.
It knows its parent construct, if any, and its nesting depth.
