Use the registers g1 and g5 as temporaries for making far jumps and far calls,
...
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown
memory in other functions, standard libraries, and worse.
In addition, this has the benefit of improving JIT performance because we
eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2
stores.

1. Bug fix: was using SLL instead of SLLX for ULongTy. Chump.
...
2. Handle fp-to-uint conversions directly here instead of relying on
a pre-transformation to replace them with the 2-step conversion.
3. Use size rather than explicitly checking types when deciding what
opcodes to use, wherever possible. This is less error prone (the
bug fix above was not the first time!).
4. Float-to-pointer casts shd now work though this hasn't been tested.

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()
