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.

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.

Canonicalize -1 - x to ~x.

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.
