AArch64: Don't lower ISD::SELECT to ISD::SELECT_CC
Instead of lowering SELECT to SELECT_CC which is further lowered later
immediately call the SELECT_CC lowering code. This is preferable
because:
- Avoids an unnecessary roundtrip through the legalization queues with
an intermediate node.
- More importantly: Lowered operations get visited last leading to SELECT_CC
getting visited with legalized operands and unlegalized ones for preexisting
SELECT_CC nodes. This does not hurt the current code (hence no testcase) but
is required for another patch I am working on.
