Authentication-results: sourceware.org; auth=none

Hello!

Currently, gcc emits wrong warning for MMX argument passing on 32 bit
targets, even when MMX is enabled:

pr59405.c: In function ‘foo32x2_be’:
pr59405.c:7:1: warning: SSE vector argument without SSE enabled
changes the ABI [enabled by default]
 foo32x2_be (float32x2_t x)

Attached patch fixes this oversight.

The testcase also tests correct function of necessary _mm_empty intrinsic.

Bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32} and
