a1a7148c4d Another API change to MRegisterInfo::foldMemoryOperand. Instead of a
MachineBasicBlock::iterator take a MachineInstr*.

39354c99a1 Change MRegisterInfo::foldMemoryOperand to return the folded
instruction to make the API more flexible.

bb07ef97cf The prologue/epilogue related method calls have no reason to return a value,
make them return void.

This allows us to avoid some costly MBB.size() calls

024126ee23 Change interface so that we can add to the end of a basic block
without getting an assertion from ilist that we are dereferencing
ilist<T>::end().

c0b9dc5be7 Change MachineBasicBlock's vector of MachineInstr pointers into an
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

e668dab5b3 Change all machine basic block modifier functions in MRegisterInfo to
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

removed EBP from the list of callee-saved registers (it isn't one).

a361c8417b storeReg2RegOffset() and loadRegOffset2Reg() now take the iterator by value
instead of by reference, since they return the modified iterator.

it is target-independent.

b83b28697c Add definitions for function headers from MRegisterInfo.h:
Some functions are in X86RegisterInfo.cpp, others, because of the data they
need, are in X86RegisterClasses.cpp, which also defines some register classes:
byte, short, and int.
