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

f57b845547 * Rename MethodPass class to FunctionPass 
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
  - Method is now const
  - It now takes one AnalysisUsage object to fill in instead of 3 vectors
    to fill in
  - Pass's now specify which other passes they _preserve_ not which ones
    they modify (be conservative!)
  - A pass can specify that it preserves all analyses (because it never
    modifies the underlying program)
* s/Method/Function/g in other random places as well

4876209aa6 Don't record instructions for copying method arguments in the 
AddedInstrns sets for the first machine instruction.  It is hard
to ensure that the right order is preserved, and sure enough, the
order was broken.  Instead, use a separate set for the function entry.

296b7730e3 * Eliminate the LiveVarSet class, making applyTranferFuncForMInst a static 
function in the one .cpp file that uses it.  Use ValueSet's instead.

  templates that will eventually be moved to Support.
* Eliminate some irrelevant const's
