libgcc_s: export integer and floating point __aeabi_ symbols

Browse source 
Export all integer and floating point __aeabi_ functions defined by
"Run-time ABI for Arm Architecture" from libgcc, excluding __aeabi_h2f_alt,
__aeabi_f2h_alt and __aeabi_d2h_alt, which are not yet implemented by
compiler-rt.

To maintain ABI backward compatibility, convert __aeabi_ floating-point
symbols previously exported from libc to an explicit non-default version.

Remove guessing of vfp/not-vfp version  for compiler-rt sources. The vfp
version needs additional runtime logic to select the right implementation
and we don't have it implemented.
