Perform a program clone at the end of parsing to remove any unreachable AST nodes.
Actually fixing the parser to never create these looks like a huge amount of work.

The built-in function "mix" in WGSL should be translated into the
intrinsic function "lerp" in HLSL according to the HLSL document.
With this patch the dawn sample CubeReflection will be able to run
correctly with tint generator on D3D12 backend.

This reverts commit e6307e5100.
Reason for revert: This change assumes that vertex shaders do not return void, but the validation for this is currently disabled since CTS still has vertex shaders that return void.
