Remove unused floating-point configuration from gmp-impl.h.
This patch removes the IEEE_DOUBLE_BIG_ENDIAN and IEEE_DOUBLE_MIXED_ENDIAN macros from gmp-impl.h and gmp-mparam.h, and the ieee_double_extract union from gmp-impl.h. The macros were used only in defining the union, which was used nowhere in glibc. As GMP's gmp-impl.h is over 5000 lines, the file in glibc is so far from the GMP version that it doesn't seem to make sense to keep things there that are not relevant in glibc. (I expect there is plenty more in the header after this patch that is also not relevant in glibc and can be cleaned up later.) Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch.
