df6d4f358a KT-22274 report warning on labels that can't be referenced 
Labels are meaningful only if they can be referenced by 'break',
'continue', or 'return' expressions.

5cb949ad7f Fix language features in tests for gradual migration to 1.3 (part 2) 
In 1.3, due to changes in language, testdata for some tests can be
different from 1.2

We want to simlultaneously test both versions, so instead of fixing
language version in such tests, we split them into two: one with fixed
1.2, another with fixed 1.3

9891f562cc [NI] Make subtyping algorithm more robust to error types 
During subtyping/incorporation we transform types (e.g. changing nullability,
 form of the type) and, basically, we're doing this to some FIXPOINT.
 It's important that we use `KotlinType.hashCode()` to compare types, but
 for error types hashCode is a hashCode of its supertype and, for example,
 `makeNullableAsSpecified` method recreate type every time. So, we continue
 to generate new constraints and we'll never stop incorporation algorithm

1f9d56439a Fix KNPE caused by optimizations in control-flow analysis 
The problem is that when performing full analysis we do it in
a backward order while result for trivial vals is filled
in a forward one.

It turns out that reversedInstuctions might return a superset of
forward traversed instructions, e.g. in case of dead code in lambda.

At the same time result for trivial vals is constant
for any instruction, thus we can just return its constant value
and use it in the full analysis

c31b5beb9e Remove redundant check for a variable being initialized after write 
It's anyway is obvious for write instruction, while effectively
after optimizations we treat val with syntactic initializer
uninitialized until their immediate initiazer

527daced46 Optimize CFG for cases of simple variables 
Parameters/vals with an immediate initializer (which we assume is a
rather common situation) do not require any kind of complicated CFA

- Unused vals can be simply determined by linear traversal of
  the pseudocode
- Definite assignment is a bit more complicated: a read-instruction of val
  can be considered as a safe if it's located *after* the first write in
  the pseudocode. It works almost always beside the case with do/while
  (see the test changed). This case will be fixed in the further commits

The test for kt897.kt will also be fixed further, all other changes
might be considered as minor as they mostly change diagnostics for
already red code

2b27e64fc8 Improve diagnostics for "not yet supported in inline" 
- Tell user what exactly is not supported (e.g., local inline function)
- Reduce diagnostics range to a keyword or an identifier
  where appropriate
