All the MIPS3D patterns were testing the wrong condition:
TARGET_PAIRED_SINGLE_FLOAT rather than TARGET_MIPS3D. I think this
has been latent since the MIPS3D support was added, but it was shielded
by the definitions of the built-in functions, which require TARGET_MIPS3D.
We now use these patterns for the autovectoriser too, and various
vect.exp tests were failing on mipsisa64-elf because we were trying
to use addr.ps on a non-MIPS3D target.
Tested on mipsisa64-elf and mips64-linux-gnu. Applied.
At some point we might want to run the vectoriser tests with -mips3d,
but this bug shows why running with plain -mpaired-single is useful too.
