af399a6ffe XFAIL this test. It only worked before because of a bug in the spill point selection code. Not deleting because 
it should be possible to enhance the selection code to handle this in the future.

3ef4549d9d Correct the algorithms for choosing spill and restore points so that we don't try to insert loads/stores between call frame setup and the actual call. 
This fixes the last known failure for the pre-alloc-splitter.

6e1bb38fb8 - Add DebugLoc to getTargetNode().

(The light-weight wrappers are only temporary. The non-DebugLoc version will be
removed once the whole debug info stuff is finished with.)

e5af2d3a22 Make x86's BT instruction matching more thorough, and add some 
dagcombines that help it match in several more cases. Add
several more cases to test/CodeGen/X86/bt.ll. This doesn't
yet include matching for BT with an immediate operand, it
just covers more register+register cases.

f560ffae1f Make isOperationLegal do what its name suggests, and introduce a 
new isOperationLegalOrCustom, which does what isOperationLegal
previously did.

Update a bunch of callers to use isOperationLegalOrCustom
instead of isOperationLegal. In some case it wasn't obvious
which behavior is desired; when in doubt I changed then to
isOperationLegalOrCustom as that preserves their previous
behavior.

This is for the second half of PR3376.
