a74e3d8a1c As pointed out by Duncan, I accidentally dropped the first MemoryFence of the

138a53b303 Change class' public PassInfo variables to by initialized with the 
address of the PassInfo directly instead of calling getPassInfo.
This eliminates a bunch of dynamic initializations of static data.

Also, fold RegisterPassBase into PassInfo, make a bunch of its
data members const, and rearrange some code to initialize data
members in constructors instead of using setter member functions.

ff2ce95673 Speedup and simplify pass registration by the observation that there is 
exactly one PassInfo object per RegisterPass object and that their lifetimes
are the same.  As such, there is no reason for the RegisterPass object to
dynamically allocate the PassInfo object at compiler startup time: just inline
the object by-value.  This should reduce codesize, heap size, and startup time. Yaay.

3acc541d97 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

b771939ef3 Two problems with these lines of code: 
1. The "work" was not in the assert, so it was punishing the optimized release
 2. getNamedFunction is _very_ expensive in large programs.  It is not designed
    to be used like this, and was taking 7% of the execution time of the code
    generator on perlbmk.

Since the assert "can never fail", I'm just killing it.
