76ee6f70ea Significant changes to correctly spill CC registers and to correctly 
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
   Also, cpMem<->Reg functions now return a vector of machine instructions.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
   needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
   since regs used to save values *across* an instruction are not obvious
   either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
   This is needed for conditional move operations.
   So an operand may need spill code both before and after the instruction.

Other changes:
-- Added several get{Class,Type} functions.
-- Added unified-to-local register number conversion.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.
-- Suggest/Color methods may modify the MachineInstr (and always did),
   so don't make that argument const!
-- Caller-saving code doesn't need its special purpose code for
   handling CC registers since cpMem<->Reg handle those correctly now.

c9a0ca5171 MachineInstr* in vector are not const (and never really were) 
because operands may be modified directly to set register.
Also, class MachineCodeForBasicBlock is now an annotation on BasicBlock.

0baf1c0911 A single MachineInstr operand may now be both a def and a use, 
so additional dep. edges have to be added.
This was needed to correctly handle conditional move instructions!

Renamed "earliestForNode" to "earliestReadyTimeForNode".

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

d23a229c4c 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.

function calls were simply wrong; other functions were just not
using all available registers.

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.
