[PATCH] ARM IAS: support .inst directive

I've just been scarred for life by digging into what goes on.
Apparently the linker gets the job of swapping the byte order on all
instructions back to little-endian, so the swapping *is* needed.

Other than that, I've just got one more small point (the rest looks
fine to me). The error message ""inst.w operand is too big" seems to
be printed in ARM mode, where it's a bit misleading.

Cheers.
