Chris Lattner 8acdca64fd - Eliminate provably non-pointer nodes from graphs.
This helps a lot of testcases, for example:
            New Time  New #Nodes     Old Time    Old #Nodes
254.gap:    91.1024     21605        91.1397     22657
povray31:    2.7807      8613         3.0152     10338
255.vortex:  1.2034      8153         1.2172     8822
moria:        .6756      3150          .7054     3877
300.twolf:    .1652      2010          .1851     3270

Typically, testcases which use long and ulong integers a lot get better, f.e. povray above.

Chris Lattner ddd3b7fa54 Don't put integer pointers (longs) into the scalar map.
This speeds stuff up by 10% on some tests, woot!

Chris Lattner a17866894a Move node forwarding code from being inlined to being out-of-line.
This brings a 11.6% speedup to steens, and a 3.6 overall speedup to ds-aa

Chris Lattner 0eee7eb390 * Fix a bug where global incompleteness marking would not mark the global
itself incomplete!
* Allow incompleteness callers to specify they don't want globals to be
  considered sources of incompleteness.

Chris Lattner 80614ee5ef Implement optimization for direct function call case. This dramatically
reduces the number of function nodes created and speeds up analysis by
about 10% overall.

Chris Lattner 5965bbb02f Fix a bug where we would incorrectly delete globals which had edges to alive nodes in
a graph in the t-d pass.  This slows down the TD pass by quite a bit (1/3), but is
needed for correctness.
