dc2ec004f1 This should fix the bug seen with some registers not being allocated 
correctly: skipping instructions by incorrectly incrementing the pointer.

Also adds support for building a reg-to-regclass map, and splits the function
for saving register to stack into two, one suitable for virtual registers
(which also assigns it a physical register) and one for simply storing back
physical registers.

a2bae305fb Remove separate vector of implicit refs from MachineInstr, and 
instead record them as extra operands in the operands[] vector.
Also, move CallArgsDescriptor into this class instead of making it an
annotation on the machine instruction.

cf911de3c6 Significant improvement: GEP used by a load or store no longer generates 
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

  revision 1.1

  New preselection pass that specializes LLVM code for a target machine,

  information and type safety.

85af131d9e Unary Not (boolean and bitwise) is no longer a separate LLVM instruction 
but is instead implemented with XOR.  Note that the InstrForest opLabels
for Not and BNot remain the same, i.e., the XOR is recognized and
represented as a (boolean or bitwise) Not when building the instruction
trees.  But these tree nodes are now binary, not unary.

f5af636dbe 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.
-- 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.
-- 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!
MachineCodeForBasicBlock is now an annotation on BasicBlock.
Renamed "earliestForNode" to "earliestReadyTimeForNode".

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.

1871b2f1c2 MachineInstr* in vector are not const (and never really were) 
because operands may be modified directly to set register.
