[interpreter] Fix self-healing with preserved bytecode.

This fixes the self-healing mechanism for closures in the interpreter
entry trampoline not that bytecode can be preserved even when baseline
code is already available.

Only for a single architecture so far, but I wanted to get your take on the
general approach before I do the architecture ports. WDYT?

[rmcilroy, 2016-08-18 13:03:50]

Approach looks good, thanks.

Added architecture ports and a test case. This should be ready for prime time.
PTAL.
