[ARM] 3252/1: help gcc do the best with ___arch__swab32
Patch from Nicolas Pitre
Depending on your gcc version, the current C-only implementation would
produce suboptimal code, ranging from a bad register selection forcing
an additional mov instruction to a failure to merge the eor and the ror
in a single instruction. With a little help gcc always produces the
best code.
