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.
