Austin Clements 97b3ce430b runtime: make gcTestMoveStackOnNextCall not double the stack 
Currently, gcTestMoveStackOnNextCall doubles the stack allocation on
each call because stack movement always doubles the stack. That's
rather unfortunate if you're doing a bunch of stack movement tests in
a row that don't actually have to grow the stack because you'll
quickly hit the stack size limit even though you're hardly using any
of the stack.

Fix this by adding a special stack poison value for
gcTestMoveStackOnNextCall that newstack recognizes and inhibits the
allocation doubling.
