Incorporate the insertion point into the key of SCEVExpander's CSE map.
...
This helps it avoid reusing an instruction that doesn't dominate all
of the users, in cases where the original instruction was inserted
before all of the users were known. This may result in redundant
expansions of sub-expressions that depend on loop-unpredictable values
in some cases, however this isn't very common, and it primarily impacts
IndVarSimplify, so GVN can be expected to clean these up.
This eliminates the need for IndVarSimplify's FixUsesBeforeDefs,
which fixes several bugs.

fix a really subtle bug in the cross section of aliases and TLS:
...
the SelectionDAG::getGlobalAddress function properly looks through
aliases to determine thread-localness, but then passes the GV* down
to GlobalAddressSDNode::GlobalAddressSDNode which does not. Instead
of passing down isTarget, just pass down the predetermined node
opcode. This fixes some assertions with out of tree changes I'm
working on.
