...for -mpaired-single at least. Although the patch shows the intention
of making this specific to -mpaired-single, we don't distinguish between
integer and float capabilities, so the condition effectively triggers
for Loongson integer vectors too.
The patch is still correct for floats on Loongson, and the Loongson
results are messy even without this patch, so I'm afraid I'm going
to punt on them for now and concentrate on getting the standard ISA
results clean. The lack of feedback to Richard's autovectorisation
patches makes me wonder how much interest there is in Loongson these
days anyway.
Tested on mipsisa64-elf and mips64-linux-gnu. Applied.
