Support strtof64x, wcstof64x aliases.
This patch adds support for defining strtof64x, strtof64x_l, wcstof64 and wcstof64x_l function aliases when _Float64x is supported. Tested for x86_64, including in conjunction with _Float64x support patches, and also tested build for other configurations (in conjunction with _Float64x support patches) with build-many-glibcs.py to cover the various different files needing updating to define these aliases. * stdlib/strtold.c [__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/float128/strtof128.c: Include <bits/floatn.h>. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/float128/strtof128_l.c [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro.

Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro.
