  PowerPC: Rename "float-abi" module flag to "long-double-type" (#210817)

PPC was emitting a "float-abi" module flag for indicating the type of
long double. The "float ABI" naming is already widely taken by soft vs. 
hard float controls (e.g., the clang flag is called -mfloat-abi), so this 
shouldn't have  taken it. This should also not be PPC specific; x86 has 
the same problem. Rename  the flag to the more specific 
long-double-type,  and  add appropriate verification and documentation 
(which was also missing).  Also  changes the value names to match the IR 
type names.
