X87: [Interpreter] Support compiling for baseline on return from interpreted function.

  port f241a61a3409cef1f8d631d5c3ee992e182f294e (r36360)

  original commit message:
  We cannot tier up from interpreted to baseline code when there is an
  activation of the function on the stack. This significantly regresses
  the performance of recursive functions since they are unlikely to get
  tiered up.

  This CL adds the ability for a function to be marked for baseline
  compilation when it returns. To do this we patch the
  InterpreterEntryTrampoline return address to point to
  InterpreterMarkBaselineOnReturn, which leaves the
  interpreted frame and recompile the function for
  baseline.

  This improves the score of EarlyBoyer by ~8x for Ignition.
