84e5185cbd Add a new -enable-cygwin-compatible-output argument, which make the output more 
consumably by the cygwin assembler.  This is really just a nasty hack until we
get real target triple support.

e599cf3856 Print % signs before register names; turn off "noprefix" mode in gas output. 
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.

e5d4f11e14 Fixed a segfault in gccld. 
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().

just PreSelection
* Wrapped code at 80 columns

ea0aa3f793 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.

33b0d331f0 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.

1d6e2b25c6 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.

2f831da9af 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()
