3d3067bf6b The big change here is to handle printing/emission of X86II::MRMSrcMem
instructions.  Right now the only users are load instructions, and Misha's
spill code

b83b28697c Add definitions for function headers from MRegisterInfo.h:
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.

076c1f923b Implement a new mergeInGraph method, which basically factors code out of
the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
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.

2fdaddf445 Fix two problems:
* Load Implementation can cause unaligned memory accesses, which caused

  * cast from pointer to pointer would zero the upper 32 bits of the pointer
