float128_private.h redefines ieee754.h identifiers ieee854_long_double
and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from
ieee754_float128.h.
This causes problems when ieee754.h is included after
float128_private.h and it's a version of ieee754.h that also defines
those identifiers; specifically, sysdeps/ieee754/ieee754.h, which
defines those identifiers for the x86 extended format. This patch
fixes this by ensuring an include of ieee754.h from float128_private.h
before the redefinitions.
Tested for x86_64 (in conjunction with float128 patches). Committed.
