This change extends the addressing mode optimization pass to HVX vgather. This is specifically intended to resolve compiler not generating indexed addresses for vgather stores to vtcm. Changed the vgather pseudo instructions to accept an immediate operand and handled addition of appropriate immediate operand in addressing mode optimization pass.
