AArch64: Add CMP+CSEL and CMP+CSET for cores that support it
GCC 15 added two new fusions CMP+CSEL and CMP+CSET.
This patch enables them for cores that support based on their Software
Optimization Guides and generically on Armv9-A. Even if a core does not
support it there's no negative performance impact.

New.
