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

it is target-independent.

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.

61ff02982f Fix logical error in TD pass: we should clear Mod/Ref bits of each caller
before inlining their graphs into a function.  To support this,
added flags to CloneFlags to strip/keep Mod/Ref bits.

9a96428297 (1) Bug fix that was causing nodes with dangling references to be freed.
We run removeDeadNodes() on the TD graph up front before using it.
(2) Major enhancement to printing of results: now we list the actual objects
    that are mod/ref instead of just printing the bit vectors.
Also an important bug fix in TDDataStructures pass (no change here):
clear Mod/Ref bits of callers before inlining into a function.

586aa3c801 Pass to compute various statisics related to DSGraphs.
For now, this just computes the #indirect call sites and
the avg. #callees per indirect call site (actually it prints
both totals and the average is their ratio).

5190ce8374 Fix two bugs:
* The globals vector was getting broken and unsorted, this caused vortex
   to get badly pessimized
 * Node offset handling was being handled really poorly, and in particular
   we were not merging types with offsets right.  This causes several graphs
   to be non-merged.

aa8146f5c4 * Dramatically rework liveness evaluation.
* Implement the first step of the Globals graph: Deleting nodes from function
  graphs.  In practice, these nodes need to be moved to the globals graph, but
  this will be taken care of later.  Note that the graphs computed right now are
  not strictly correct!

* Aggressively fold calls together if we inlined a graph that provides
  call nodes.
* Add a bailout if the current graph has over 200 call nodes in it, this is
  a really whacky case that should never happen.
