r303188 removed all the uses of aliases for EABI functions from
compiler-rt, because some of them had mismatched calling conventions.
Obviously, we can't use aliases for functions which don't have the same
calling convention, but that's only an issue for floating-point
functions with the hardfloat ABI. In other cases, the stubs increase
size and reduce performance for no benefit.
This patch adds back the aliases, with appropriate checks to make sure
they're only used in cases where the calling convention matches.

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!

This adds hard-float implementation for the following builtins:
* __fixdfdi()
* __fixsfdi()
* __fixunsdfdi()
* __fixunssfdi()
The soft-float implementation does never raise floating point
exceptions, which doesn't allow clients to detect floating point
conversion errors.
I must mention that I had to refer to libgcc's implementation to
write these functions.
Related unit-tests of compiler-rt passed with these changes.
Patch was somewhat out-dated, so was updated locally without any
functional changes.

80bit Intel/PPC long double is excluded due to lacking support
for the abstraction. Consistently provide saturation logic.
Extend to long double on 128bit IEEE extended platforms.
Initial patch with test cases from GuanHong Liu.
