Completely eliminate the per-machine-instruction regsUsed set.
...
This substantially shrinks the size of each machine instruction, which should
make allocation faster and the cache footprint of the machine code lighter.
Here are some timings for code generation of the larger benchmarks we have.
This are timings of code generation phases of the X86 JIT, when compiled in
debug mode:

(1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes
...
to clone the subgraph reachable from a set of root nodes, into the
current graph, merging the global nodes into those in the current graph.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
globals graph into the current graph in both BU and TD passes.
(3) Added hash_set<const GlobalValue*> InlinedGlobals: a set of globals to
track which globals have been inlined into the current graph from
callers or callees. In the TD pass, such globals are up-to-date and
do not need to be rematerialized from the GlobalsGraph.
(4) Added StripIncompleteBit/KeepIncompleteBit to remove incomplete bit
when cloning nodes into the globals graph.
