  [AArch64][SVE] Add integer arithmetic with immediate instructions.

Summary:
Add pattern matching for the following instructions:
- add, sub, subr, sqadd, sqsub, uqadd, uqsub

This patch required complex patterns to match the immediate with optinal left shift.

I re-used the Select function from the other SVE repo to implement the complext pattern.

I plan on doing another patch to also match constant vector of the same immediate.
