80d79fa5b4 If we can't find INT64_MAX, set it to a reasonable default value, 
instead of printing out an (incorrect) #error message.

5e8b77e375 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:

a2dd745613 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!
