3ceac85296 Include llvm/CodeGen/MachineCodeForInstruction.h. Use it to start 
implementing verifySavedState().

In saveState(), use the new AllocInfo::AllocStateTy enum, and increment
Insn each time through the loop.

82c5eb7bc8 Make AllocState an enum. 
Move the stringifying method for that enum into class AllocInfo.

8fc493430c Publicize the type of FnAllocState. 
Prototype option to save state in a global instead of as a Constant in
 the Module. (Turned off, for now, with the on/off switch welded in the off
 position. You get the idea.)

537132bf12 Move AllocInfo structure to a private AllocInfo.h header file. 
Make FnAllocState contain vectors of AllocInfo, instead of LLVM Constants.
Give doFinalization a method comment, and let it do the work of converting
 AllocInfos to LLVM Constants.

60a3c55c4f Don't worry about converting each function's reg. alloc. state into One Big 
Constant early on, because we can do it in doFinalization.

dac9131e28 Preselection is _not_ a basicblock pass, because it adds global variables to 
the module.  This change converts it from being a basic block pass to being
a simple pass.  This allows elimination of the annotation and simplification
of the logic for moving constants into global variables.

43a5ff8d40 Emit x86 instructions for: A = B op C, where A and B are 16-bit registers, 
C is a constant which can be sign-extended from 8 bits without value loss,
and op is one of: add, sub, imul, and, or, xor.

This allows the JIT to emit the one byte version of the constant instead of
the two or 4 byte version.  Because these instructions are very common, this
can save a LOT of code space.  For example, I sampled two benchmarks, 176.gcc
and 254.gap.

BM        Old     New    Reduction
176.gcc 2673621 2548962  4.89%
254.gap  498261  475104  4.87%

Note that while the percentage is not spectacular, this did eliminate
124.6 _KILOBYTES_ of codespace from gcc.  Not bad.

Note that this doesn't effect the llc version at all, because the assembler
already does this optimization.
