Remove conversion of fp-to-uint cast into a multi-step cast:
...
this is not an optional transformation on SPARC and is now handled
directly by instruction selection.

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()

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:

Switched from using diff to cmp for two reasons:
