x86: Don't disable SSE4a when disabling SSE4
commit 7deea9aad8 changed nosse4 to include CpuSSE4a. But AMD SSE4a is
a superset of SSE3 and Intel SSE4 is a superset of SSSE3. Disable Intel
SSE4 shouldn't disable AMD SSE4a. This patch restores nosse4. It also
adds .sse4a and nosse4a.
gas/
* config/tc-i386.c (cpu_arch): Add .sse4a and nosse4a. Restore
nosse4.
* doc/c-i386.texi: Document sse4a and nosse4a.
opcodes/
* i386-gen.c (cpu_flag_init): Add CPU_ANY_SSE4A_FLAGS. Remove
CPU_ANY_SSE4_FLAGS.
