Chris Lattner 74bc5c7147 There was no reason for these to be bit-fields, they just need to be unique. 
Also, add an isVoid item

Chris Lattner 385a6b2589 Completely eliminate the per-machine-instruction regsUsed set. 
This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.

Here are some timings for code generation of the larger benchmarks we have.
This are timings of code generation phases of the X86 JIT, when compiled in
debug mode:

Chris Lattner cd4f4320b0 All callers of these methods actually wanted them to preserve the flags, 
so get rid of the def/use parameters that were getting passed in.

**** This now changes the semantics of these methods to preserve the flags,
     not clobber them!

Chris Lattner 2a5dae05e6 Including statistics into an anonymous namespace that gets #included into
