814819f6ea stop using the .lcomm pseudoop on darwin, instead, directly use the
.zerofill directive.  Streamerize its generation.

74bfe21b50 Now that we have everything nicely factored (e.g. asmprinter is not
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:

619ea855e7 more cleanups. Emit the .local directive even on cygwin/mingw.
I'm not sure that this is correct, but it causes no test failures,
and just emitting a .comm without protecting its linkage somehow
is surely not right.

48d64ba9d8 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.

c7fbe90389 fix a significant difference between llvm and gcc on ELF systems:
GCC would put weak zero initialized mutable data in the .bss section,
we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' 
section.  Fixing this will allow simplifications next up.

a3839bc371 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.

aac138e84d 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.

eb231ce51d The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in
the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
indirect branch).  Instead of '1', it should be specified as '?', because GPR
only specifies the register class, which includes both hi-and-lo registers.
