Fixes test case test/Programs/LLVMSource/2003-08-03-ReservedWordGlobal.ll.

Also: Refactor implicit-uses printing into its own method.
Remove a couple of unused variables.

The original code does not work because the value from WorkList.end() is
invalidated once WorkList.erase() is called.  To ensure proper functionality,
we must ensure that WorkList.erase() is always called before WorkList.end().

* Wrapped code at 80 columns

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.

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.

this is not an optional transformation on SPARC and is now handled
directly by instruction selection.

* 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()
