relocations and add a routine to ensure that we don't put the
addresses in an offset table for split dwarf.

Since we'll now also need the split dwarf file name along with the
language in DwarfTypeUnits, just use the whole DICompileUnit rather than
explicitly handling each field needed.

Use an if statement instead of a pair of ternary operators checking
the same condition.
Use a cheap method call rather than returning the local symbol.

r198196: Use a pointer to keep track of the skeleton unit for each normal unit and construct it up front.
r198199: Reapply r198196 with a fix to zero initialize the skeleton pointer.
r198202: Fix aranges and split dwarf by ensuring that the symbol and relocation back to the compile unit from the aranges section is to the skeleton unit and not the one in the dwo.
with a fix to use integer 0 for DW_AT_low_pc since the relocation to the text section symbol was causing issues with COFF. Accordingly remove addLocalLabelAddress and machinery since we're not currently using it.

back to the compile unit from the aranges section is to the skeleton
unit and not the one in the dwo.
Do this by adding a method to grab a forwarded on local sym and local
section by querying the skeleton if one exists and using that. Add
a few tests to verify the relocations are back to the correct section.

routine so that we're not needlessly using an indirction in the case
of split dwarf.
Update testcases according to the new ordering of attributes on
the compile unit.

This simplifies type unit and type unit reference creation as well as
setting the stage for inter-type hashing across type unit boundaries.

This commit does not complete the type units feature - there are issues
around fission support (skeletal type units, pubtypes/pubnames) and
hashing of some types including those containing references to types in
other type units.
Originally committed as r197073 and reverted in r197079.
Recommitted as r197197 to reproduce the failure and reverted as r197199
Turns out there was unstable ordering in the type unit dumping code.
Fixed by using MapVector in DWARFContext to store the debug_types
comdat sections.
Recommitted as r197210 with a fix to dumping and reverted as r197211
because I was a bit gun shy and thought I saw a failure that turned out
to be unrelated.
So here we go - once more with feeling! \o/

This commit originally got jumbled up with another build-breaking commit
and I can't find the failures I thought this caused anymore.
Recommitting to hopefully get some clean buildbot results to work from.
I have a sneaking suspicion there's unstable output in the comdat group
output of MCStreamer...

This reverts commit r197073.
The test seems to be failing on some buildbots for unknown reasons.
Reverting until I can figure that out. If anyone's got a reproduction
(.s and .o together would be great) - I'd really appreciate it.

This removes another case of spooky action at a distance (building the
same label names in multiple places creating an implicit dependency
between those places) and helps pave the way for type units.

This is a precursor to moving type units into the correct (debug_types)
section with comdat groups and full type unit headers.
