[PATCH] D29413: [Assembler] Add a pointer to the inline assembly SourceMgr in MCContext.

[Sanne Wouda via Phabricator via llvm-commits]

sanwou01 created this revision.

This allows for proper error messages through the inline assembly
SourceMgr.  The AsmPrinter's life time includes the MCContext's life
time.
