[PATCH] D12347: [MC/AsmParser] Avoid setting MCSymbol.IsUsed

[Saleem Abdulrasool via llvm-commits]

compnerd added a comment.

It is unfortunate that these accessors mutate the symbol.  Personally, I think I prefer the alternate approach of a RAII helper that would restore the state.  However, if you are planning some follow up work and this blocks forward progress, then committing this as is to make forward progress would be acceptable (thanks to the annotations).

Thanks for fixing up the test.
