[ARM][Compiler-rt] Fix AEABI builtins to correctly pass arguments to non-AEABI functions on HF targets
Summary:
This is a patch for PR34167.
On HF targets functions like `__{eq,lt,le,ge,gt}df2` and `__{eq,lt,le,ge,gt}sf2` expect their arguments to be passed in d/s registers, while some of the AEABI builtins pass them in r registers.
