Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas.
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.

Chris Lattner 298d2f090f Make sure to verify the result before writing out the bytecode file. Not doing
so can cause obscure errors downstream.

Chris Lattner 52b4fb3fde Reorder passes a bit. In particular, it makes sense to run globaldce IMMEDIATELY after funcresolve. Also, run the mem2reg pass _early_ so that IPCP and DAE actually do stuff.
Run instcombine and simplify cfg after this to cleanup the intraprocedural messes we create.

Chris Lattner 4973805acd The levelraise pass is a broken old piece of crufty code that should be
left on the side of the road without a second thought.

It is preventing forward progress, so for now, we will disable it by default.

  cleaned up.  This is also important because scalar replacement of aggr.
  will want instcombine to run before it goes as well.

Vikram S. Adve 9c485d2165 gcc3.1.1 seems much more selective about what it loads from archives, and
does not link in many passes that are loaded by gcc2.95.3.  So use object
