131161bc6e Rename AliasSet to SubRegs, to reflect changes in the surrounding code.

7ddcadc7ee Move the include of MachineLocation.h into MachineModuleInfo.h 
because it declares a std::vector<MachineMove>, and strict
concept checking requires the definition of MachineMove to be
available.

2276a7bc8e Teach instcombine's visitLoad to scan back several instructions 
to find opportunities for store-to-load forwarding or load CSE,
in the same way that visitStore scans back to do DSE. Also, define
a new helper function for testing whether the addresses of two
memory accesses are known to have the same value, and use it in
both visitStore and visitLoad.

These two changes allow instcombine to eliminate loads in code
produced by front-ends that frequently emit obviously redundant
addressing for memory references.

3358629380 Now that predicates can be composed, simplify several of 
the predicates by extending simple predicates to create
more complex predicates instead of duplicating the logic
for the simple predicates.

This doesn't reduce much redundancy in DAGISelEmitter.cpp's
generated source yet; that will require improvements to
DAGISelEmitter.cpp's instruction sorting, to make it more
effectively group nodes with similar predicates together.

0540e17788 Add support for having multiple predicates on a TreePatternNode. 
This will allow predicates to be composed, which will allow the
predicate definitions to become less redundant, and eventually
will allow DAGISelEmitter.cpp to emit less redundant code.

160f6cc209 Some minor cleanups: 
1. Compute action in X86SelectSelect based on MVT instead of type.
2. Use TLI.getValueType(..) instead of MVT::getVT(..) because the former
   handles pointers and the later doesn't.
3. Don't pass TLI into isTypeLegal, since it already has access to it as 
   an ivar.

#2 gives fast isel some minor new functionality: handling load/stores of
pointers.
