[MC] Implement EmitRawText in MCNullStreamer

Authored by eush on Oct 31 2018, 9:40 AM.



This adds dummy implementation of EmitRawText in MCNullStreamer.

This fixes the behavior of AsmPrinter with MCNullStreamer on targets
on which no integrated assembler is used. An attempt to emit inline asm
on such a target would previously lead to a crash, since AsmPrinter does not
check for hasRawTextSupport in EmitInlineAsm and calls EmitRawText
anyway if integrated assembler is disabled (the behavior has changed
in D2686).

Error message printed by MCStreamer:

EmitRawText called on an MCStreamer that doesn't support it, something
must not be fully mc'ized

LGTM. It makes sense to me that MCNullStreamer supports raw text by not emitting anything.
