and emitted per function and CU. Begins coalescing ranges as a first
class entity through debug info. No functional change.

Header/cpp file rename to follow immediately - just splitting out the
commits for ease of review/reading to demonstrate that the renaming
changes are entirely mechanical.

ARanges included even extern variables referenced by pointer non-type
template parameters even though that variable isn't part of this
compilation unit.

Since type units aren't in the CUMap, use the DwarfUnits list to iterate
over units for tasks such as accelerator table building.

r195698 moved the type unit checking up into getOrCreateTypeDIE so
remove the redundant check and fold the functions back together again.

It might be possible to eventually use one data structure, but I haven't
looked at the exact criteria used for accelerator tables and pubtypes to
see if there's good reason for the differences between the two or not.

This avoids the need for an extra list of SkeletonCUs and associated
cleanup while staging things to be cleaner for further type unit
improvements.
Also hopefully fixes a memory leak introduced in r195166.

a non-relocatable number offset.
One fixme to make the ranges as discrete data structures and
have range lists explicitly represented rather than as a list of symbols.

section use the form DW_FORM_data4 whilst in Dwarf 4 and later they
use the form DW_FORM_sec_offset.
This patch updates the places where such attributes are generated to
use the appropriate form depending on the Dwarf version. The DIE entries
affected have the following tags:
DW_AT_stmt_list, DW_AT_ranges, DW_AT_location, DW_AT_GNU_pubnames,
DW_AT_GNU_pubtypes, DW_AT_GNU_addr_base, DW_AT_GNU_ranges_base
It also adds a hidden command line option "--dwarf-version=<uint>"
to llc which allows the version of Dwarf to be generated to override
what is specified in the metadata; this makes it possible to update
existing tests to check the debugging information generated for both
Dwarf 4 (the default) and Dwarf 3 using the same metadata.

While not strictly necessary (the class has an invariant that
"setDebugInfoOffset" is called before "getDebugInfoOffset" - anyone
client that actually gets the default zero offset is buggy/broken) this
is consistent with the code as originally written and the removal of the
initialization was an accident in r195166.

Emit DW_TAG_type_units into the debug_info section using compile unit
headers. This is bogus/unusable by debuggers, but testable and provides
more isolated review.
Subsequent patches will include support for type unit headers and
emission into the debug_types section, as well as comdat grouping the
types based on their hash. Also the CompileUnit type will be renamed
'Unit' and relevant portions pulled out into respective CompileUnit and
TypeUnit types.
