x86: correct "length_immediate" in a few cases
When first added explicitly in 3ddffba914b2 ("i386.md
(sse4_1_round<mode>2): Add avx512f alternative"), "*" should not have
been used for the pre-existing alternative. The attribute was plain
missing. Subsequent changes adding more alternatives then generously
extended the bogus pattern.
Apparently something similar happened to the two mmx_pblendvb_* insns.
gcc/
* config/i386/i386.md (sse4_1_round<mode>2): Make
"length_immediate" uniformly 1.
* config/i386/mmx.md (mmx_pblendvb_v8qi): Likewise.
(mmx_pblendvb_<mode>): Likewise.
