Chris Lattner 915c5f9862 Switch the code generator (except the JIT) onto the new DebugLoc
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

Benjamin Kramer 74729ae094 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

Devang Patel bd477bef25 Refactor code to push DILocation prcessing into DwarfDebug.cpp from AsmPrinter.cpp.
This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions.

Devang Patel 53e91f0836 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.

Chris Lattner 27a9732450 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.
