about 10% overall.

706e7ab871 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.

e12c74c07b This file implements a pass that automatically parallelizes a program, 
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.
