Chris Lattner 124dc743bc implement mc asmparser support for '.', which gets the
current PC.  rdar://7834775

We now produce an identical .o file compared to the cctools
assembler for something like this:

_f0:
L0:
        jmp L1
        .long . - L0
L1:
        jmp A
        .long . - L1

        .zerofill __DATA,_bss,A,0

// FIXME: For now this test just checks that llvm-mc -triple i386-unknown-unknown works. Once we have .macro,
// .if, and .abort we can write a better test (without resorting to miles of
// greps).
// RUN: llvm-mc -triple i386-unknown-unknown %s > %t
