7351e3a364 add a bool for whether .lcomm takes an alignment instead of basing this on "isdarwin".

f904832189 hoist handling of external globals and special globals up to common code. 
This makes a similar code dead in all the other targets, I'll clean it up
in a bit.

This also moves handling of lcomm up before acquisition of a section,
since lcomm never needs a section.

b5e64bd377 use BSSLocal classifier to identify 'lcomm' data instead of 
duplicating the logic (differently) in lots of different targets.

and everything else (weak).

77f12b9ee0 introduce a section kind for common linkage. Use this to slightly 
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

816fcd1287 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.

5678a9711b - Add a comment to the callback indicating that it's *extremely* not a good 
idea, but unfortunately necessary.
- Default to using 4-bytes for the LSDA pointer encoding to agree with the
  encoded value in the CIE.

d7bd67fa61 Change CurrentFnSym to be a non-const pointer since asmprinter mutates it 
as it emits code.  Switch .globl directives to use OutStreamer instead of
doing it textually (in x86)

6f360c3c91 now that MCSymbol::print doesn't use it's MAI argument, we can 
remove it and change all the code that prints MCSymbols to use 
<< instead, which is much simpler and cleaner.

f7c6508544 Get MCSymbol out of the mangling business, and move all the logic 
to Mangler.  Now MCSymbol just decides whether to slap quotes around
a symbol when printing it.

This also fixes some weirdness where two MCSymbols could be created
for the same symbol, if one needed to be mangled and got mangled to
the other one.

d78fcdd332 Retrying r91337: 
The CIE says that the LSDA point in the FDE section is an "sdata4". That's fine,
but we need it to actually be 4-bytes in the FDE for some platforms. Allow
individual platforms to decide for themselves.

b1b91d11db supplement CurrentFnName with CurrentFnSym, which will eventually
