<pre>ISD::LOAD handling for ComputeKnownBits/NumSignBits only handle basic EXTLOADs
and range metadata.
It'd be useful to be able to extract constant pool data, including target
specific wrappers such as X86ISelLowering's getTargetConstantFromNode.
This would help ComputeKnownBits/NumSignBits users work with constant vectors
after legalization.</pre>
