fe14568a81 Make data structure acurately get ALL edges, even loads of null fields of
nodes that are not shadow nodes

This fixes em3d to be _correct_ if not optimial

7650b94c75 * Remove the concept of a critical shadow node
* Make the function pointer argument explicit for a call nodes
* Eliminate unreachable global values
* Merge call nodes that are identical

212be2e569 * Eliminate ArgDSNode's completely, now rely on scalar map
* Fold call nodes that are indistinguishable for each other.  This is a big
  win for external functions like sqrt, which would multiply dramatically
  before.
* Global nodes with no edges to or from them are now eliminated from the graph.

by the call node noncritical before the call is destroyed.

0b7c85c06a Unify the destruction code used for node pairs vs normal nodes. This was
causing a problem before because global values with incoming edges didn't
copy the incoming edges to the node they were being merged from, causing
the poolalloc pass to die.

someplace nicer in the file though.

doesn't resort!
* Be more generous with the cached matches that we allow now.
* Recursive calls should all work now!

1120c8b34a Many changes
* Simplify a lot of the inlining stuff.  There are still problems, but not
  many
* Break up the Function representation to have a vector for every different
  node type so it is fast to find nodes of a particular flavor.
* Do more intelligent merging of call values
* Allow elimination of unreachable shadow and allocation nodes
* Generalize indistinguishability testing to allow merging of identical calls.
* Increase shadow node merging power

2ba3a72c3a * Add #define to enabled debug messages
* Move removeEdgesTo to be a member of DSNode
* Implement (but #ifdef out) the new, spiffier, method of determining
  shadow node equivalence.  This cannot be enabled until more is
  implemented.
