d0aa0cdbc6 Change MachineBasicBlock's to not be Annotations, instead they are kept as
part of a linked list tracked by MachineFunction.  MachineBasicBlock::get
is now linear time instead of constant time, and thus is deprecated!

572f5c8c0c Fairly major overhaul of MachineInstr & Operand classes
- Inline methods that are mostly a single line anyway
  - Eliminate several methods that were never called
  - Group methods a bit more consistently

deb9654056 Interface to class MachineCodeForBasicBlock.
Moved here from MachineInstr.h to make it an annotation on BasicBlock.

7a4be9580e Moved class MachineCodeForBasicBlock to MachineCodeForBasicBlock.{cpp,h}.
An (explicit or implicit) operand may now be both a def and a use.
Also add a set of regs used by each instruction.
dump() no longer takes an optional argument, which doesn't work in gdb.

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

7b3640bd12 Optional args are no longer allocated as they are discovered.
(This can be improved to avoid making the initial pass over the method.)
Also, ensure automatic vars and reg. spills areas are not extended
if their sizes are used for computing some other offset.

6111a87b3a Move the InsertPrologEpilogCode class out of the Sparc.cpp file into the
new PrologEpilogCodeInserter.cpp file, and include the bodies of the
GetInstructionsFor(Prolog|Epilog) functions from SparcInstrSelection.cpp
into the class.  This eliminates the need for a static global vector of
instructions and a class of errors that is really unneccesary.
