Adding fenv support for ARM

[Eshan Dhawan]

Hi
I am testing another approach for this, Creating a new header fenv-vfp.h.
And add all the inline assembly as well as the static inline functions to
that file.
calling it from fenv-vfp.c instead of fenv.c.
fenv-vfp is the one file that has the main ARM specific code.
Fenv.c is the file that calls the vfp functions.
I will keep the results posted. :)
