Subject: [PATCH] Revert "nir/spirv: Update to the 1.0 GLSL.std.450 header"

This reverts commit b33f5d388979f23c583c78f10a18a941cb04ce04,
and also removes the (empty) case statements for the new built-ins.

It doesn't look like glslang has updated yet, so updating the header
just breaks everything, as we no longer agree on opcode numbers.
