Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting

unused functions (I didn't want to delete code without review) and unused

issues when they see them. All changes pass DejaGnu tests and Olden.

2. Added partial debug support for mingw\cygwin targets (the same as
Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format
for storing debug info by default, thus many (runtime) libraries has
this information included. These formats shouldn't be mixed in one binary
('stabs' & 'DWARF'), otherwise binutils tools will be confused.

adds assertions that check to make sure every operand gets emitted.

Fix a long-standing wart in the code generator: two-address instruction lowering
...
actually *removes* one of the operands, instead of just assigning both operands
the same register. This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.
Changing this also gets rid of a bunch of hacky code in various places.
This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.

Completely rearchitect the interface between targets and the pass manager.
...
This pass:
1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
output, move all this to common code, and give targets hooks they can
implement.
3. Commonalize the target population stuff between file emission and JIT
emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
paves the way for "fast -O0" stuff in the CFE later, and now LLC could
lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
which is now orthogonal to the fact that JIT'ing is being done.

Oops. Bad typo. Without the check of N1.hasOneUse() bad things can happen.
...
Suppose the TokenFactor can reach the Op:
[Load chain]
^
|
[Load]
^ ^
| |
/ \-
/ |
/ [Op]
/ ^ ^
| .. |
| / |
[TokenFactor] |
^ |
| |
\ /
\ /
[Store]
If we move the Load below the TokenFactor, we would have created a cycle in
the DAG.
