[AMDGPU] Extend the SI Load/Store optimizer

Summary:
Extend the SI Load/Store optimizer to merge MIMG load instructions. Handle
different flavours of image_load and image_sample instructions.

When the instructions of the same subclass differ only in dmask, merge
them and update dmask accordingly.
