265752ae8f 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.

ac2de0424b 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.

6ec98952e0 Readonly/readnone functions are allowed to throw 
exceptions, so don't turn invokes of them into
calls.

7a8a7099b1 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.

6690b9499b Fix handling of overflow in loop calculation by adding new UDiv SCEV. This SCEV 
is disabled in the sense that it will refuse to create one from a UDiv
instruction, until the code is better tested.
