51a4911121 New CSEMap datastructure impl
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29555 91177308-0d34-0410-b5e6-96231b3b80d8

a5682853b9 Revamp the "CSEMap" datastructure used in the SelectionDAG class. This
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a
home-grown hashtable.

This is still a work in progress: not all the maps have been moved over and the
hashtable never resizes.  That said, this still speeds up llc 20% on kimwitu++
with -fast -regalloc=local using a release build.

09fd736058 AssignTopologicalOrder now returns the vector of SDNode* by reference to
avoid the expensive operation of copying a vector.
It also returns a maximum id by value.

9ff542f2cc 1. Change use of "Cache" to "Default".
2. Added argument to instruction scheduler creators so the creators can do
special things.
3. Repaired target hazard code.
4. Misc.

More to follow.
