the heuristic would result in dynamic alignment code being generated when

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.

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.

Instcombine does this but apparently there are situations where this pattern will escape the optimizer and / or created by isel. Here is a case that's seen in JavaScriptCore:
%t1 = sub i32 0, %a
%t2 = add i32 %t1, -1
The dag combiner pattern: ((c1-A)+c2) -> (c1+c2)-A
will fold it to -1 - %a.
