Saleem Abdulrasool 5852d6bc57 MCAsmParser: support .ifne 
The .ifne directive assembles the following section of code if the argument
expression is non-zero.  Effectively, it is equivalent to if.

Daniel Dunbar d0c6d361fe MC/AsmParser: Attempt to constant fold expressions up-front. This ensures we avoid fixups for obvious cases like '-(16)'.

Kevin Enderby d9f952948e Added Mac OS X assembler style conditional assembly. I may come back and see if 
I can clean this up a bit more and do way with the TheCondState and just use
the top element on the TheCondStack if not empty.  Also may tweak the code
around ParseConditionalAssemblyDirectives() to simplify the AsmParser code.
