c09e411102 llvm-mc: A few more parsing / match tweaks. 
- Operands which are just a label should be parsed as immediates, not memory
   operands (from the assembler perspective).

 - Match a few more flavors of immediates.

 - Distinguish match functions for memory operands which don't take a segment
   register.

 - We match the .s for "hello world" now!

46b754c76b add some comments on how this is *supposed* to work. We don't 
need the PreferredEHDataFormat hook, but I have yet-more refactoring to
do before I can zap it.

bef8768bd0 Simplify operand padding by keying off tabs in the asm stream. If 
padding is disabled, tabs get replaced by spaces except in the case of
the first operand, where the tab is output to line up the operands after
the mnemonics.

Add some better comments and eliminate redundant code.

Fix some testcases to not assume tabs.

7a01e95915 PreferredEHDataFormat is always call with data and global, but this whole 
thing is #if0'd out anyway.  Just simplify the code by reducing the interface.
Not deleting this is essential for Bill's continuing happiness.

1db511cc91 remove the PPCLinuxTargetAsmInfo implementation of PreferredEHDataFormat, 
because it just calls the default impl.

Remove the PPCDarwinTargetAsmInfo version of PreferredEHDataFormat because
it just returns DW_EH_PE_absptr unless on 10.6.  However, 10.6 doesn't support
PPC, so the default impl is just fine.
