[Mesa-dev] [PATCH v2 3/4] spirv: Add a 64-bit implementation of OpIsInf

[Neil Roberts]

The only change neccessary is to change the type of the constant used
to compare against.

This has been tested against the arb_gpu_shader_fp64/execution/
fs-isinf-dvec tests using the ARB_gl_spirv branch.

v2: Use nir_imm_floatN_t for the constant.
