  Changed paths:

    M llvm/test/CodeGen/AArch64/GlobalISel/arm64-irtranslator.ll
    M llvm/test/CodeGen/AArch64/GlobalISel/call-translator-tail-call.ll
    A llvm/test/CodeGen/AArch64/arm64-preserve-most.ll

  Log Message:
  -----------
  When lowering calls and tail calls in AArch64, the register mask and
return value location depends on the calling convention of the callee.
`F.getCallingConv()`, however, is the caller CC. Correct it to the
callee CC from `CallLoweringInfo`.

Fixes PR43449
