  -----------
  AArch64: Move AArch64MCExpr functions to AArch64MCAsmInfo

To migrate away from the legacy
XXXMCExpr::printImpl/evaluateAsRelocatableImpl overrides and align with
other targets.

While the AArch64MCAsmInfoXXX hooks introduce some duplication, they
enable better separation for object file formats.

Note: While AArch64MCAsmInfoDarwin uses the `@specifier` notation, it
might use AArch64MCExpr with specifier VK_ABS.
test/tools/llvm-mca/AArch64/Exynos/zero-latency-move.s abuses a parser
behavior that :lo12: is also parsed for Mach-O (though it will fail for
-filetype=obj).
