Support avx512f in __builtin_cpu_supports.
gcc/
* config/i386/cpuid.h (bit_MPX, bit_BNDREGS, bit_BNDCSR):
Define.
* config/i386/i386.c (get_builtin_code_for_version): Add avx512f.
(fold_builtin_cpu): Ditto.
* doc/extend.texi: Documment it.
gcc/testsuite/
* g++.dg/ext/mv2.C: Add test for target ("avx512f").
* gcc.target/i386/builtin_target.c: Ditto.
libgcc/
* config/i386/cpuinfo.c (processor_features): Add FEATURE_AVX512F.
* config/i386/cpuinfo.c (get_available_features): Detect it.
