c2db1a95df * Simplify code a bit by breaking the PHI node handling stuff out into a seperate 
function from normal regalloc code
* Make the regalloc for a block a function instead of part of runOnMachineBB, which
  makes it easier to see what's going on in runOnMBB.

972b03fa53 This should be more correct: invalidates physical registers that are used in 
an instruction to avoid using them to allocate to other virtual registers.

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.

part of a linked list tracked by MachineFunction.  MachineBasicBlock::get
is now linear time instead of constant time, and thus is deprecated!

  - Eliminate several methods that were never called
  - Group methods a bit more consistently

27a08935ca - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

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).

1632e882f1 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.
