i386: Remove broadcasts from TARGET_MMX_WITH_SSE vec_dup insn patterns
XMM broadcast instructions broadcast value from general reg to all
elements of the vector. This is not allowed for TARGET_MMX_WITH_SSE,
where it is expected that bits outside lower 64bits load or retain
zero value. Following testcases expect broadcast, and are thus invalid:

FAIL: gcc.target/i386/sse2-mmx-18b.c scan-assembler-times pbroadcastd 1
FAIL: gcc.target/i386/sse2-mmx-19b.c scan-assembler-not movd

FAIL: gcc.target/i386/sse2-mmx-19e.c scan-assembler-times pbroadcastw 1
These testcases are removed entirely.
