Recently I've fixed two wrong FP vector negate implementation which
caused wrong sign bits in zeros in targets (r14-8786 and r14-8801). To
prevent a similar issue from happening again, add a test case.
Tested on x86_64 (with SSE2, AVX, AVX2, and AVX512F), AArch64, MIPS
(with MSA), LoongArch (with LSX and LASX).
gcc/testsuite:
* gcc.dg/vect/vect-neg-zero.c: New test.

- v1 -> v2: Remove { dg-do run } which may cause SIGILL.
- v2 -> v3: Add -fno-associative-math to fix an excessive warning on
arm.
Ok for trunk?
OK
