This PR fixes assertion failures when stepping in the Mono debugger on ARM64 by aligning the breakpoint address calculation logic with the AMD64 implementation. The changes remove the division by 4 that was causing incorrect indexing into the breakpoint addresses array.

* Ensure domain assembly is non-null in CordbModule

Long-running enumerator loops at Tier0+instr will see their executions
transition over to a non-instrumented OSR version of the code.

This can cause loss of PGO data in the portions of the method that
execute after the leaving the loop that inspires OSR.

For enumerator vars we can safely deduce the likely classes from
probes made earlier in the method. So when we see a class profile
for an enumerator var, remember it and use it for subsequent calls
that lack their own profile data.
