when a method (or a property getter) returns Nothing, emit
ACONST_NULL
ATHROW
after a call so that class files verifier knows that this is an exit point in a method.
Note that if an inline method returning Nothing throws an exception explicitly
(or via a chain of inline methods), this code will be deleted by DCE.
Parse TryCatchBlockNode's in generated bytecode, infer stack save/restore points.
Save stack to local variables before 'try'.
Restore stack after the beginning of try-block, catch-block, and default handler.
Integrate before/after inline markers rewriting (otherwise it'll break our stacks).
#KT-3309 Fixed
- generate fake jump instructions so that we can always analyze stack depths
- fix stack before break and continue by dropping excessive elements (e.g., *a*.foo(*b*, c?:continue))
- Analyzer rewritten in Kotlin, with more flexible control of CFG traversal

And String.length as well.
This is done for JVM interoperability: java.lang.CharSequence is an open class
and has a function 'length()' which should be implemented in subclasses
somehow.
A minor unexpected effect of this is that String.length() is now a compile-time
constant (it wasn't such as a property because properties are not supported in
compile-time constant evaluation)
#KT-3571 Fixed
This is not something that needs to be intrinsified. Note that compiler
optimizations are still possible and the fact whether 'indices' is a member or
an extension is irrelevant to the optimizer
#KT-3574 Fixed
Do not assert that resolvedCall is non-null, since getRangeAsBinaryCall can
return a BinaryCall that doesn't represent a range at all (as specified by the
comment in getRangeAsBinaryCall)
The condition of a do-while loop can use variables declared in the loop
(variables can only be declared inside a block). Previously this behaviour
caused crash because after the block was generated, all variables declared
inside that block were gone from myFrameMap
