58ba50fea7 * Renamed option from nopreselect' to nopreopt' since it disables more than 
just PreSelection
* Wrapped code at 80 columns
* Added the DecomposeMultiDimRefs Pass to the JIT compilation path

0870e970ff 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.

e895a740c7 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.

5ac1175ada 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.

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()

72666e6c30 Add all arithmetic operators to ConstantExprToString(). 
Note that some generated operators (like &, | or ^) may
not be supported by the assembler -- but if they've got
this far, it's better to generate them and let the assembler decide.

since it is *necessary* for correct code generation.  Only optional
transformations belong in the PreOpts pass (which needs to be renamed
from PreSelection to PreOpts).
