the night realising that it was wrong :)  I
think the reason the same type was being used
for the shufflevec of indices as for the actual
indices is so that if one of them needs splitting
then so does the other.  After my patch it might
be that the indices need splitting but not the
rest, yet there is no good way of handling that.
I think the right solution is to not have the
shufflevec be an operand at all: just have it
be the list of numbers it actually is, stored
as extra info in the node.

multiply to be done as unsigned, so that they have well defined
behavior on overflow. This fixes PR2408.

Make PRE actually handle critical edges (by splitting them).  Confirmed that bootstrap passes with this change.

Renamed deterministic EvalBinOp to DetermEvalBinOpNN.  This name mangling is unfortunately needed because virtual methods with the same name can be hidden by subclasses.

llvm-svn: 53751

Modified the new EvalBinOpNN to generate states instead of nodes.  This is a much simpler interface and is what clients will want to do.

heat death of the universe, fixing an O(N^2) problem in the

Fix a leak that this turned up in LowerSubregs.cpp.
And, comment a leak in LiveIntervalAnalysis.cpp.

Provide static methods in BinaryOperator to determine if an opcode is an equality opcode, a relational opcode, or a logical opcode.

Begin major changes to EvalXXX methods in GRTransferFuncs.  Currently some of the methods only return an RVal; we want them to be able to create an arbitrary number of states.

PseudoSourceValue values, which never have names. Use getName()
for all other values, because we want to print just a short summary
of the value, not the entire instruction.
