[PATCH] ARM IAS: support .inst directive

[Renato Golin]

  Hi Saleem,

  Thanks for working on this, please update bug http://llvm.org/PR18199 after this has gone in to show that .inst is implemented (and give the commit number).

  Also, please use "diff -U999" so that we can see the context before and after each change, as this way I have to go back and forth to an editor to understand which functions and classes were changed.
