5f06e10a84 GCSE is faster than SCCP, and it makes SCCP's job easier, so run it first.

eadd32cda2 Instruction Combination can create a ton of trivially dead instructions. Remove 
them with an DIE pass before more expensive optimizations are run.

76d12299b5 Make sure that there is no case where a signal can occur leaving a partially 
written output file.  This is important because crashing testcases often write
part of a file out, and the testing harness decides the file is up-to-date next
time the test is run.

69cd2b1ade Move the PromoteMemoryToRegister pass to be run _after_ the raise pointer 
references pass, so it is given the chance to do some good!

f4de63f65f Implement a more powerful, simpler, pass system. This pass system can figure 
out how to run a collection of passes optimially given their behaviors and
charactaristics.

Convert code to use it.
