51cf15cf12 * Rename const_regclass_begin/end to just regclass_begin/end 
* Regclass iterators need an extra level of pointerness to work right
* Pull inverse mapping code out of target description files

8ea96d8162 This file provides the function DemoteRegToStack(), which takes a 
virtual register computed by an Instruction& X and replaces it with
a slot in the stack frame, allocated via alloca.

c8ea11cf8e The pass Parallelize automatically parallelizes a program using the 
Cilk multi-threaded runtime system to execute parallel code.  This file
exposes some routines needed for code generation for that pass.

b5bdad135e Several fixes: 
(1) Applied patch from Casey to implement iterator::operator= correctly:
    it should use a pointer, not a reference.
(2) Added operators == and !=, and method all().
(3) Important bug fix: excess bits need to be ignored in operations
    like ==, count(), and all().  We do this by ensuring excess bits
    in the last bitset are always 0.

940cfa8597 Instead of checking op.getType() against MO_VirtualRegister and 
MO_MachineRegister, we no longer distinguish Virtual vs. Machine registers
externally, they're ALL registers, all equal.

Registers are only differentiated whether they are >=
MRegisterInfo::FirstVirtual or not.

b5027095e5 - Eliminated the deferred symbol table stuff in Module & Function, it really

fbaf9e7ad0 SSARegMap -- the mapping between SSARegisters and their RegisterClasses, which 
imply types of SSA Registers. This is on a per-function basis, so the
MachineFunction contains the SSARegMap, and has accessor functions to it.
