3c802de01a MC/AsmParser: Add .macros_{off,on} support, not that makes sense since we don't 
support macros.

9f2ad11624 Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and not 
CurPtr[0] == '\n' when testing the character after a "0b" when looking
to see if it part of a something like "jmp 0b".

d8ba292c9b Fixed the problem with a branch to "0b" that was not parsed by llvm-mc 
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".

525a3a67c1 llvm-mc: Support reassignment of variables in one special case, when the 
variable has not yet been used in an expression. This allows us to support a few
cases that show up in real code (mostly because gcc generates it for Objective-C
on Darwin), without giving up a reasonable semantic model for assignment.

  movl $a, %eax
  movl $$a, %eax
