MC/Mach-O: Implement initial support for relaxation.
...
- The implementation is currently very brain dead and inefficient, but I have a
clear plan on how to fix it.
- The good news is, it works and correctly assembles 403.gcc (when built with
Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
the resulting binary is exactly equivalent to that when built with the system
assembler. So it probably works! :)

This is the second patch to allow x86 code to be aligned with optimal nops.
...
With the compiler changed to use EmitCodeAlignment() it does change the
functionality. But X86 assembly code assembled with llvm-mc does not change
its output. For that we will eventually change the assembler frontend to
detect a '.align x, 0x90' when used in a section that 'hasInstructions' and use
EmitCodeAlignment, but will wait until we have better target hooks.

This is the first patch to put the needed bits in place to eventually allow code
...
to be aligned with optimal nops. This patch does not change any functionality
and when the compiler is changed to use EmitCodeAlignment() it should also not
change the resulting output. Once the compiler change is made and everything
looks good the next patch with the table of optimal X86 nops will be added to
WriteNopData() changing the output. There are many FIXMEs in this patch which
will be removed when we have better target hooks (coming soon I hear).

give MCAsmInfo a 'has little endian' bit. This is unfortunate, but

I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.
I may change this in the future, we'll see how it works out.

Cleanup handling of .zerofill on darwin:
...
1. TargetLoweringObjectFileMachO should decide if something
goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
the right MCSection, the asmprinters should just emit to the
right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
MAI can have a bool "haszerofill" instead of having the textual
directive to emit.
