improves readability of the call handling code significantly, as well as
makes it clear which parts are hacky (externals) and which parts are good
(call handling).

No functionality change.

1. Hash not quite right for DIEValues.

2. Not going to use Usage (no significant benefit.)

Remove unused variables.

llvm-svn: 31381

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

General clean up of teh dwarf writer.

1. Most significant is the folding of debug information entries.  This
reduced self hosted -g SelectionDAGISel.s from 120M to 13M and pretty
close to matching .o file sizes with gcc.

2. Debug information entry printing for debugging the dwarf code.

3. Bring all the code closer to llvm standards.

4. Misc. fixes and doc clean ups.
