Fangrui Song f727ae92f5 [MC] Make MCStreamer aware of AsmParser's StartTokLoc
A SMLoc allows MCStreamer to report location-aware diagnostics, which
were previously done by adding SMLoc to various methods (e.g. emit*) in an ad-hoc way.

Since the file:line is most important, the column is less important and
the start token location suffices in many cases, this patch reverts
