aarch64: Emit csinv again for `a ? ~b : b` [PR110986]

After r14-3110-g7fb65f10285, the canonical form for
`a ? ~b : b` changed to be `-(a) ^ b` that means
for aarch64 we need to add a few new insn patterns
to be able to catch this and change it to be
what is the canonical form for the aarch64 backend.
A secondary pattern was needed to support a zero_extended
form too; this adds a testcase for all 3 cases.

Bootstrapped and tested on aarch64-linux-gnu with no regressions.
