[Bug target/35757] New: [4.4 Regression] Incorrect contraint on sse4_1_blendp<ssemodesuffixf2c>

[hjl dot tools at gmail dot com]

sse.md has

(define_insn "sse4_1_blendp<ssemodesuffixf2c>"
  [(set (match_operand:SSEMODEF2P 0 "register_operand" "=x")
        (vec_merge:SSEMODEF2P
          (match_operand:SSEMODEF2P 2 "nonimmediate_operand" "xm")
          (match_operand:SSEMODEF2P 1 "register_operand" "0")
          (match_operand:SI 3 "const_0_to_3_operand" "n")))]
  "TARGET_SSE4_1"
  "blendp<ssemodesuffixf2c>\t{%3, %2, %0|%0, %2, %3}"
  [(set_attr "type" "ssemov")
   (set_attr "prefix_extra" "1")
   (set_attr "mode" "<MODE>")])

The problem is blendpd takes 0 to 15 as immediate operand. The problem
is hidden in testsuite due to MAEK defined in sse4_1-check.h.
