afeca1f7f6 - DSGraph Printing Improvements: 
* Print edge source labels again
     * Override node shape to be Mrecord again, instead of just record.

8845b7da14 - Generic graph printing infrastructure changes: 
* Only print outgoing edges from a cell if the destination isn't null.
       This is important for DSGraphs, which have sources with no edges.
     * Allow Node attributes to override shape of the node

3a54b695ce 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).

b16f596ab4 Allow emission of names that start with an underscore. This is needed to 
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

33988dc76d There is no way to guarantee that constants are not forward referenced. 
Handle forward referenced constants in a general way.  This fixes bug:
Assembler/2002-10-13-ConstantEncodingProblem.llx and allows the SPEC
197.parser benchmark to be built

82f54dca49 - Change Function's so that their argument list is populated when they are 
constructed.  Before, external functions would have an empty argument list,
    now a Function ALWAYS has a populated argument list.

e18a54c249 Use vectors instead of hash_maps for issueGaps and conflictLists.
