float128: Add conversion from float128 to mpn
Reuse the code for __mpn_extract_long_double to implement __mpn_extract_float128. * include/gmp.h: Include bits/floatn.h (__mpn_extract_float128): Declare when __HAVE_DISTINCT_FLOAT128 is 1. * stdlib/gmp-impl.h: Also check if alloca is not defined before including stack-alloc.h. It could have been defined by other header which not necessarily defines HAVE_ALLOCA. * sysdeps/ieee754/float128/Makefile: New file. * sysdeps/ieee754/float128/float1282mpn.c: New file. * sysdeps/ieee754/float128/float128_private.h: Include gmp.h before redefining __mpn_extract_long_double to __mpn_extract_float128, then redefine __mpn_extract_long_double to __mpn_extract_float128. * sysdeps/ieee754/ldbl-128/ldbl2mpn.c: Replace long double with _Float128 to allow float128_private.h overrides.
