46e24d4492 Remove usage of noncopyable classes to clean up doxygen output. 
In particular these classes are the last that link the noncopyable classes
with the hash_map, vector, and list classes.

2d906f4550 Changes to allow explicit physical register arguments that have been 
preallocated.  While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

681b3c77fa (1) Added special register class containing (for now) %fsr. 
Fixed spilling of %fcc[0-3] which are part of %fsr.

(2) Moved some machine-independent reg-class code to class TargetRegInfo
    from SparcReg{Class,}Info.

(3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly()
    and related functions and flags.  Fixed several bugs where only
    "isDef" was being checked, not "isDefAndUse".

e18a54c249 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

4efbb9c931 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!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".

536cf1b13f * 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

119c675af7 * Add a file header with some information 
* Delete the DelaySlotInfo objects created by the SchedulingManager class.
  These leaked objects were accounting for 3/4 of the memory leaked by the
  backend, so this is a relatively major win.
* Reorganize SchedulingManager::getDelaySlotInfoForInstr so that it has
  better code locality (making it easier to read).

cd23d94446 Clean up the ownership model a bit so that nodes actually get deleted more 
frequently. This still leaks edges quite a bit, but it leaks no nodes
(I think).

0cdcf40121 Add option to disable scheduling. 
Destroy live-variable information after scheduling so it is
recomputed before later phases (e.g., reg. allocation).
