Step into method with optimized loops freezes the debugger

[guillep]

This one is funny :)

"Execute this"
OpalCompiler compile: 'foo
	[1] repeat'.

"Debug this (cmd+shift+D) and step into #foo"
OpalCompiler new foo.

• Debug the second expression step into foo
• Freeze!

The debugger tries to step until the next "interesting bytecode".
But! This just loops, so the debugger keeps looping.
The next interesting bytecode is the return after the loop.
But this is an infinite loop.

Scope of the issue

We have seen this with repeat but also with whileTrue:/whileFalse:
