Chris Lattner b25abcb1fa If we see: 
%A = alloca int
  %V = load int* %A

value number %V to undef, not 0.

client has another VN implementation that can VN calls.

Chris Lattner e3f247bcac In a "seeing the forest through the trees" kinda situation, I realized that a 
complete rewrite of load-vn will make it a bit faster.  This changes speeds up
the gcse pass (which uses load-vn) from 25.45s to 0.42s on the testcase in
PR209.

I've also verified that this gives the exact same results as the old one.

Chris Lattner d3e4d81ad7 This is a big diff with no functionality change. We just reorder some code, 
which causes big reindentation.  While I'm at it, I fix the fixme by removing
some dead code.
