review(M): 7057120: Tiered: Allow C1 to inline methods with loops

[Igor Veresov]

This allows inlining of methods with loops by C1 on levels with 
profiling (2 and 3). The solution is to recompile the enclosing methods 
without inlining of the method that has OSRed to level 4 or recompile 
the enclosing method at level 4.

There's no significant impact on performance because of these changes.

The change is for 7u2.

Thanks,
