a9963c648e Don't die with an assertion if the Result bitwidth is already correct. This 
fixes an assert reading "1239123123123123" when the result is already 64-bit.

098c595dd2 Limit the number of times we recurse through this algorithm. All of the 
intructions are processed. So there's no need to look at them if they're used as
operands of other instructions.

4c7972d638 Simplify code by converting multiple places that were manually concatenating 128-bit vectors to use either CONCAT_VECTORS or a helper function. CONCAT_VECTORS will itself be lowered to the same pattern as before. The helper function is needed for concats of BUILD_VECTORs since getNode(CONCAT_VECTORS) will just return a large BUILD_VECTOR and we may be trying to lower large BUILD_VECTORS when this occurs.

a3e3481c57 Tidy up this test more: 
1) Make the checked assertions a bit more precise. We really want the
   canonical forms coming out of reassociate to be exactly what is
   expected.
2) Remove other passes, and switch the test to actually directly check
   that reassociate makes the important transforms and
   canonicalizations.
3) Fold in a related test case now that we're using FileCheck. Make the
   same tidying changes to it.

8c48e4ff89 Make ISelPosition a local variable.

ISelPosition can become a local variable in DoInstructionSelection.

bc7d448f24 Register DAGUpdateListeners with SelectionDAG. 
Instead of passing listener pointers to RAUW, let SelectionDAG itself
keep a linked list of interested listeners.

This makes it possible to have multiple listeners active at once, like
RAUWUpdateListener was already doing. It also makes it possible to
register listeners up the call stack without controlling all RAUW calls
below.

DAGUpdateListener uses an RAII pattern to add itself to the SelectionDAG
list of active listeners.

c0ccb8bb17 SparseSet: Add support for key-derived indexes and arbitrary key types. 
This nicely handles the most common case of virtual register sets, but
also handles anticipated cases where we will map pointers to IDs.

The goal is not to develop a completely generic SparseSet
template. Instead we want to handle the expected uses within llvm
without any template antics in the client code. I'm adding a bit of
template nastiness here, and some assumption about expected usage in
order to make the client code very clean.

The expected common uses cases I'm designing for:
- integer keys that need to be reindexed, and may map to additional
  data
- densely numbered objects where we want pointer keys because no
  number->object map exists.
