[PATCH] x86: fix SSE4a dependencies of ".arch .nosse*"

[Jan Beulich]

Since ".arch sse4a" enables SSE3 and earlier, disabling SSE3 should also
disable SSE4a. And as per its name, ".arch .nosse4" should also do so.

	* config/tc-i386.c (cpu_noarch): Use CPU_ANY_SSE4_FLAGS in
	"nosse4" entry.

	* i386-gen.c (cpu_flag_init): Move CpuSSE4a from
	CPU_ANY_SSE_FLAGS entry to CPU_ANY_SSE3_FLAGS one. Add
	CPU_ANY_SSE4_FLAGS entry.
	* i386-init.h: Re-generate.
