0897c60822 SparcV9CodeEmitter.cpp:
* Doxygen-ified comments
* Added capability to make far calls (i.e., beyond 30 bits in CALL instr)
  which implies that we need to delete function references that were added by
  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)
* Cleaned up code that generates far jumps by using an array+loop

SparcV9CodeEmitter.h:
* Explained more of the side-effects of emitFarCall()

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:

cb048097c9 Reverted back to using OR for cmp/mv operations for lex/yacc output.
The shell AND/OR operators short-circuit on command success/failure, which is
the inverse of exit status (i.e. 0 means success, non-zero means failure).

75a005ff4c Switched from using diff to cmp for two reasons:
o Not all versions of diff have the -q option
	o The cmp program is probably faster than diff
Fixed the logic that only copies the file over if no differences are found.
