[AArch64] Codegen support for FEAT_PAuthLR
- Adds a new +pc option to -mbranch-protection that will enable
the use of PC as a diversifier in PAC branch protection code.
- When +pauth-lr is enabled (-march=armv9.5a+pauth-lr) in combination
with -mbranch-protection=pac-ret+pc, the new 9.5-a instructions
(pacibsppc, retaasppc, etc) are used.
Documentation for the relevant instructions can be found here:
