PR port-arm/55897
Cherry-pick upstream commit llvm-svn: 303188:
https://github.com/llvm/llvm-project/commit/36ac5ddff7377586390a71cb3261f0a40d274308#diff-549f1733063df365663fe375f336034e33e16d6bf2826cd4f966045aeb136007
----
[PATCH] builtins: expand out the AEABI function stubs
These actually may change calling conventions. We cannot simply provide
function aliases as the aliased function may have a different calling
convention. Provide a forwarding function instead to permit the
compiler to synthesize the calling convention adjustment thunk.
Remove the `ARM_EABI_FNALIAS` macro as that is not safe to use.
Resolves PR33030!
