Bit pack DIE structures better.

16 bits are sufficient to store attributes, tags and forms.

Remove generation of DW_AT_sibling. Nothing as far as I can tell uses it.

Always use the string pool, even when it makes the .o larger. This may help

tools that read the debug info in the .o files by making the DIE sizes more
consistent.

DwarfDebug: Allocate DIEValues with a BumpPtrAllocator. Most of them are

POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).
~6% less mallocs and ~1% compile time improvement on clang -O0 -g oggenc.c

DW_AT_stmt_list attribute attached with a compile unit encodes offset of line number information for this compile unit in debug_line section. This offset is always zero when only one compile unit is emitted in a object file.

simplify EmitSectionOffset to always use .set if it is

available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything. Make EmitSectionOffset call EmitDifference
instead of duplicating it.

There is no need to use FoldingSet to unique DIEs.

DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.

Split out the Dwarf writer stuff into separate files. This is a much more

logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.
Trivia: It *looks* like there would be functionality changes, however there aren't!
