  [Hexagon] Extend OptAddrMode pass to vgather

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.
