6e6026b465 - Eliminated the deferred symbol table stuff in Module & Function, it really 
wasn't an optimization and it was causing lots of bugs.

2c08dcc276 Eliminate the concept of a deferred symbol table. The optimization really isn't, 
and it causes obscure bugs to show up in passes.

4e4caeffbd Fix a nasty problem with dominance calculation for unreachable blocks. 
If we had a CFG that look like Entry -> B, Unreachable -> B, then we would
not correctly determine that Entry dominated B, because Entry did not
apparently dominate "unreachable".  This patch fixes this by making the entry
node dominate all blocks, including unreachable ones.
