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.

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.

was broken, and couldn't occur anyway.

92673296e6 Stop representing scalars as explicit nodes in the graph. Now the only 
nodes in the graph are memory objects, which is very nice.  This also greatly
reduces the size and memory footprint for DSGraphs.  For example, the local
DSGraph for llu went from 65 to 13 nodes with this change.  As a side bonus,
dot seems to lay out the graphs slightly better too.  :)

8f0a16eac6 This fixes all kinds of problems with array handling. There are still bugs to 
be fixed, but we are getting much closer now.

    * Make DSNode::TypeRec a full fledged DSTypeRec type.
    * Add methods used to update and access the typerecords elements
    * Add methods to query if and to cause a node to be completely folded
    * DSGraph construction doesn't use the allocation type for anything at all,
      now nodes get their type information based on how they are used.
    * Fixed a bug with global value handling introduced in the last checkin
    * GEP support is now much better, arrays are handled correctly.  The array
      flag is now updated in type records.  There are still cases that are not
      handled yet (we do not detect pessimizations), but getting much closer.
