_mm_insert_epi16 mistakenly.

preprocessed testcase

when I turn on the -O optimization swith,I get the wrong result:
65535	65535	65535	65535	65535	65535	65535	65535
0	0	0	0	0	0	0	0
65535	65535	65535	65535	65535	65535	65535	65535
the correct result is :
65535	65535	65535	65535	65535	65535	65535	65535
0	65535	65535	65535	65535	65535	65535	65535

if I modify the pattern of sse2_pinsrw in i386.md :22089 from vector_merge to 
unspec, the bug is fixed.
initial version:
(define_insn "sse2_pinsrw"
  [(set (match_operand:V8HI 0 "register_operand" "=x")
        (vec_merge:V8HI (match_operand:V8HI 1 "register_operand" "0")
                        (vec_duplicate:V8HI
                         (truncate:HI
                           (match_operand:SI 2 "nonimmediate_operand" "rm")))
                        (match_operand:SI 3 "const_0_to_255_operand" "N")))]
  "TARGET_SSE2"
  "pinsrw\t{%3, %2, %0|%0, %2, %3}"
  [(set_attr "type" "ssecvt")
   (set_attr "mode" "TI")])
modified version:
(define_insn "sse2_pinsrw"
  [(set (match_operand:V8HI 0 "register_operand" "=x")
        (unspec:V8HI (match_operand:V8HI 1 "register_operand" "0")
                        (vec_duplicate:V8HI
                         (truncate:HI
                           (match_operand:SI 2 "nonimmediate_operand" "rm")))
                        (match_operand:SI 3 "const_0_to_255_operand" "N")))]
  "TARGET_SSE2"
  "pinsrw\t{%3, %2, %0|%0, %2, %3}"
  [(set_attr "type" "ssecvt")
   (set_attr "mode" "TI")])

"Fixed" means a patch was checked into CVS, which apparently it wasn't.

This is still not fixed in mainline CVS. The patch would be an one-liner...
