1871b2f1c2 MachineInstr* in vector are not const (and never really were) 
because operands may be modified directly to set register.

dabb41d93d Numerous bug fixes: 
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

d0c668c380 Two Cleanups to generated C code: 
1. Avoid printing *(&globalvariable), instead print globalvariable alone
   as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
   execution characteristics of expressions.  Now we get nice (but
   over-parenthesized, oh well) things like:

     ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));

   instead of five seperate instructions (bsBuff & bsStream are globals).

* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const

    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)

    modifies the underlying program)

4911c357e1 Make LoopDeptCalculator be an internal artifact of how RegAlloc is implemented, 
do not expose it.  Additionally, have it be auto generated by the pass framework
for us.

* SparcInternals.h now no longer #includes RegClass.h or SparcRegClassInfo.h
* Pull inlined functions out of .h file if they are virtual and interfere with dependencies
