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.
