This reverts commit 830e08b98b and eb1857ce0d.
This commit leads to an unexpected failure on test/CodeGen/AArch64/sve-gather-scatter-dag-combine.ll.
The review will need more changes before its re-commited.

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.
