2c2c69c075 Added a trivial function to modify the flags field of MCSymbolData class. The function takes the value and a mask, and clears the mask bits before applying the value.

7670f69e42 MC/Mach-O x86_64: Switch to using fragment atom symbol. 
- This eliminates getAtomForAddress() (which was a linear search) and
   simplifies getAtom().
 - This also fixes some correctness problems where local labels at the same
   address as non-local labels could be assigned to the wrong atom.

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

29a7152676 Fixed a nasty layering violation in the edis source 
code.  It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.

Also removed hacky #define-controlled initialization
of targets in edis.  If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

ecdad4bb0c eliminate the magic AbsoluteDebugSectionOffsets MAI hook, 
which is really a property of the section being referenced.
Add a predicate to MCSection to replace it.

4e8e791414 add a new EmitInlineAsm function to asmprinter to handle inline asm. 
If we have an MCAsmStreamer, we continue to emit asm textually, 
otherwise we (currently) emit an error to errs and ignore it.

8e4cf6f425 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

d04906b49e llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always need 
exactly two passes in that case, and don't ever need to recompute any layout,
so this is a nice baseline for relaxation performance.

Feel free to LOL at the -before numbers, if you like.

I am a little surprised we make more than 2 relaxation passes. It's pretty
trivial for us to do relaxation out-of-order if that would give a speedup.
