  • Store a crossgeam GC collector in the BagPipe
  • Use this GC instance for pinning, eliminating the dependency on the global singleton, and thus on thread-local storage
  • Remove bsalloc dependency from elfmalloc and move it into elfc so that running elfmalloc tests is faster
  • Run elfmalloc tests with opt-level=3 in Travis

bagpipe: Store a crossbeam GC internally, don't use global singleton
b387e33 
- Store a crossgeam GC collector in the BagPipe
- Use this GC instance for pinning, eliminating the dependency on
  the global singleton, and thus on thread-local storage
- elfmalloc: Don't set bsalloc as the global allocator because the
  new GC allocates on clone, and if the global allocator is bsalloc,
  each clone call becomes very expensive, which makes tests run
  very slowly
- elfmalloc: Use opt-level=3 for tests in Travis
- elfc: Set bsalloc as the global allocator
