This patch causes following testsuite failures:

i386:
FAIL: gcc.target/i386/sse-vect-types.c (test for excess errors)

x86_64:
FAIL: gcc.target/i386/sse-13.c (test for excess errors)
FAIL: gcc.target/i386/sse-14.c (test for excess errors)
FAIL: gcc.target/i386/sse-vect-types.c (test for excess errors)

sse-13.c and sse-14.c also fail on i386 when compiled with -msse2.

The errors are:

emmintrin.h:XXX: error: shift must be an immediate
