New Revision: 199287

URL: http://llvm.org/viewvc/llvm-project?rev=199287&view=rev
Log:
Only mark functions as micromips.

The GNU as behavior is a bit different and very strange. It will mark any
label that contains an instruction. We can implement that, but using the
type looks more natural since gas will not mark a function if a .word is
used to output the instructions!
