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.

Implement the getRegForInlineAsmConstraint method for PPC. With recent
...
sdisel changes, this eliminates a ton of copies around common inline asms.
For example:
int test2(int Y, int X) {
asm("foo %0, %1" : "=r"(X): "r"(X));
return X;
}
now compiles to:
_test2:
foo r3, r4
blr
instead of:
_test2:
mr r2, r4
foo r2, r2
mr r3, r2
blr
GCC produces:
_test2:

no fixes physreg. Treat this as permission to use any register in the register
class. When this happens and it is safe, allow the llvm register allcoator to
allocate the register instead of doing it at isel time. This eliminates a ton

int test2(int Y, int X) {
