Preserve static initialization semantics for parts by introducing a special "clinit trigger" class.
Insert "static initialization trigger" call to every method of a part class, remove this call on inline.
Always mangle names for private functions in multifile class parts to avoid resolution clashes on inheritance.
NB in codegen tests initializers for all non-const vals are wrapped in 'run { ... }',
so that the initializer is not a constant expression, and some static initialization code should be generated.
See testData/simpleUnitializedMerge.kt
On exit from `if` we merge value in variable with slot 1 (x):
- from `if` body we get BoxedBasicValue
- from outer block we get UNITIALIZED_VALUE
So we just suppose `x` is unitialized after `if`
and there's no need to mark BoxedValue as unsafe to remove
because it's anyway can't be used after `if`

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.
In cases when signature of special bridge is the same as current method,
but type is not 'Any?'.
Also there is tiny optimization:
only null check needed if value parameter type is mapped to Object,
but it's not nullable.

0. Such properties are called special because their accessor JVM name differs from usual one
1. When making call to such property, always choose special name
2. When generating Kotlin class inheriting such property generate `final bridge int size() { return this.getSize(); }`
3. If there is no `size` declaration in current class generate `bridge int getSize() { // super-call }`
Annotation arguments with default values are rendered as ... if renderDefaultAnnotationArguments is true.
Tests: java retention does not taken into account by Descriptor comparator.
Java retentinon changed to kotlin retention in some tests + one new test with java retention added.
More accurate tests for intentions in byte code (visibility controlled).
For each non-abstract non-declared (i.e. inherited from supertypes) method in
an interface we generate its static form to the TImpl, which calls the TImpl
method from the corresponding supertype.
The accidental override tests changed because we're now trying to generate the
delegate for the super method, not knowing that it will clash with the declared
method
