  Log Message:
  -----------
  [Clang][ARM][AArch64] Add support for Armv9-A, Armv9.1-A and Armv9.2-A

armv9-a, armv9.1-a and armv9.2-a can be targeted using the -march option
both in ARM and AArch64.

 - Armv9-A maps to Armv8.5-A.
 - Armv9.1-A maps to Armv8.6-A.
 - Armv9.2-A maps to Armv8.7-A.
 - The SVE2 extension is enabled by default on these architectures.
 - The cryptographic extensions are disabled by default on these
 architectures.

The Armv9-A architecture is described in the Arm® Architecture Reference
Manual Supplement Armv9, for Armv9-A architecture profile
(https://developer.arm.com/documentation/ddi0608/latest).
