We can generate {v,}pinsrb in ix86_expand_vector_init_one_nonzero and
ix86_expand_vector_init_one_var. {v,}pinsrd is already generated where
optimal.

* config/i386/i386-expand.c (ix86_expand_vector_init_one_nonzero)
<case E_V8QImode>: Use vector_set path for
TARGET_MMX_WITH_SSE && TARGET_SSE4_1.
(ix86_expand_vector_init_one_var) <case E_V8QImode>:
Do not widen for TARGET_MMX_WITH_SSE && TARGET_SSE4_1.
Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.
Committed to mainline SVN.
Uros.
