Update from Gnulib
This incorporates:
2020-08-06 libgmp: add <gmp/gmp.h> support
2020-08-06 Consider that clang defines __OPTIMIZE__ like GCC does
2020-08-06 Use __builtin_expect with clang everywhere
2020-08-05 Use __builtin_clz{,l,ll} with clang, also on Windows
2020-08-05 Use __builtin_ctz{,l,ll} and __builtin_ffs{,l,ll} with clang
2020-07-31 _GL_CMP: Improve documentation
2020-07-30 alloca, largefile: sync with Autoconf master
