kmillikin@google.com 172ee045f3 Build and use stack maps in the SSA compiler.
Add a stack bitmap to the location summaries for calls that are GC
safepoints.  The bitmap covers the spill slots.  The register
allocator collects these bitmaps into a list and then marks live
pointer values during register allocation.  When emitting code for a
call, a heap-allocated stackmap is built.
