Image Operand Sample allows sparse image opcodes

Browse Source 
@ehsannas had filed an issue against SPIR-V spec, concerning
Image Operands section (3.14):
Sample
A following operand is the sample number of the sample to use. Only
valid with OpImageFetch, OpImageRead, and OpImageWrite.

Relaxing the check to allow OpImageSparseRead and
OpImageSparseFetch to fix failing tests.
