David Blaikie f4597a0cd4 DebugInfo: Move type units into the debug_types section with appropriate comdat grouping and type unit headers
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.

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...

David Blaikie 118de30ec1 Revert "DebugInfo: Move type units into the debug_types section with appropriate comdat grouping and type unit headers"
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.

ambiguous. Reformat to match.

David Blaikie b5a244bd54 DebugInfo: Include the section and start-of-section label in the unit
This is a precursor to moving type units into the correct (debug_types)
section with comdat groups and full type unit headers.

Eric Christopher fb934a2183 Use move and stack allocation for RangeSpanLists. As a result make
a few things more const as well because we're now using const
references to refer to iterators.

David Blaikie 193140b085 DebugInfo: Remove unused start/end labels for the debug_abbrevs section
Since we always emit only one abbrevation section (shared by all the
compilation units in this module) there's no need for a separate label
at the start of each one (and we weren't using the CU ID anyway, so
there really was only one label). Use the section label instead and drop
the wholely unused debug_abbrev_end label.
