MC/Mach-O: For PCrel relocations, we need to compensate for the PCrel adjustment when determining if we need a scattered relocation.

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.

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).

 - I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).

 - I haven't really tried to find the "right" way to store the fixups or apply
   them, yet. This works, but isn't particularly elegant or fast.

 - Still no evaluation support, so we don't actually ever not turn a fixup into
   a relocation entry.
