Sergey Dmitrouk f3206d6278 Add hard float versions of FP to LL conversions 
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.

Joerg Sonnenberger 91bd698eaf Refactor float to integer conversion to share the same code. 
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.
