e4dc717585 Ding dong, the DoesntAccessMemoryFns and 
OnlyReadsMemoryFns tables are dead!  We
get more, and more accurate, information
from gcc via the readnone and readonly
function attributes.

42b5e08e71 Fix a bug where we'd try to find a scev value for a bitcast operand, 
even though the bitcast operand did not have integer type.  This fixes
PR1814.

baccd5872e Fix a bug in which node A is replaced by node B, but later 
node A gets back into the DAG again because it was hiding in
one of the node maps: make sure that node replacement happens
in those maps too.
