fb8c61056f Handle bzero and memset in the local analysis, because we were missing the fact
that memset returns its argument!!

15869aa2c7 All DSGraphs keep a reference to the targetdata they are created with. This is
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

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.

BUDataStructure::CallSite is no longer needed.

97f51a3024 * Standardize how analysis results/passes as printed with the print() virtual
methods
* Eliminate AnalysisID:  Now it is just a typedef for const PassInfo*
* Simplify how AnalysisID's are initialized
* Eliminate Analysis/Writer.cpp/.h: incorporate printing functionality into
  the analyses themselves.

eef796c767 Always create a shadow node for a store instruction, even if it's storing
a scalar value.  Likewise for load instructions.

c314ac49d7 * Nodes now keep track of any global variables in them
* Only dead-node-eliminate nodes with no flags
* Don't merge scalars, only merge what they point to.
