With --target=mipsel-unknown-linux-gnu, result of "./xgcc -W -Wall -O2 -B./ -S
-I. -march=loongson2f x.c -o xo32.s"

With stdint.h in the gcc objdir, run xgcc as in description.

Note the generic-code generated for ior(), the initialization of the
output-only operand for "pshufh" in gag(), and the needless moving between
float/vector and general registers as well as using the general-register-add in
mp() except as mandated by the intrinsic.
