Optimize v4si broadcast for noavx512vl.
This will enable below
- vbroadcastss .LC1(%rip), %xmm0
+ movl $-45, %edx
+ vmovd %edx, %xmm0
+ vpshufd $0, %xmm0, %xmm0
According to microbenchmark, it's faster than broadcast from memory
for TARGET_INTER_UNIT_MOVES_TO_VEC.
gcc/ChangeLog:
* config/i386/sse.md (*vec_dupv4si): Disable memory operand
for !TARGET_INTER_UNIT_MOVES_TO_VEC when prefer_for_speed.
gcc/testsuite/ChangeLog:
* gcc.target/i386/pr100865-8a.c: Adjust testcase.
* gcc.target/i386/pr100865-8c.c: Ditto.
* gcc.target/i386/pr100865-9c.c: Ditto.
