Subject: [PATCH] Flush the raw_ostream after emitting the assembly for a
 function. This is a temporary fix for the -print-emitted-asm option, where
 errs() is used as the stream, in the case where other code is using stderr
 without using errs()' buffer. Hopefully soon we'll fix errs() to be
 non-buffered instead. Patch by Preston Gurd.
