FixStack transformation divides on phases:
- Fixing stack before break/continue
- Fixing stack for inline markers/try-catch blocks
After the first stage all ALWAYS_TRUE markers are replaced
with simple GOTO's and if we're skipping break/continue edges
we won't reach the code after while (true) statement.
At the same time it's fine to not to skip them in the second phase
as the stack for them is already corrected in the first phase

Note that this isn't fully correct, consider the following situation:
S : T, T : Any?
=> CS(S, T) = T, but for now it will be T?, which is reliable but not so specific as just T
Problem manifests when a class property name matches a companion object
property name, and class property is referenced in closure context.

SAM interface wrapper for an argument is required,
if in the function descriptor for SAM adapter
type for the corresponding value parameter
doesn't match type of the corresponding value parameter
in the original (Java) descriptor.

Do the same thing as for secondary constructor (looks like it was a
workaround for R&I bug that was used only for secondary constructors
for some reason).

If 'this' (implicit or explicit) was used as an extension receiver,
and the corresponding call required a smart-cast,
this information was effectively lost in "old" resolution & inference,
but is required by "old" JVM BE to generate proper CHECKCASTs.
This makes sense for non-floating-point primitive type
(boolean, char, byte, short, int, long):
floating-point types use specialized versions of 'areEqual'.
The problem is that now that the local delegated property metadata is in
the $$delegatedProperties array of the containing class, the access to
it from code calling an inline function with a local delegated property
is illegal.
Currently it seems to be a lot of work to support this rather rare case
properly (see the comment in ExpressionCodegen.getVariableMetadataValue)
so we postpone it and return the old behavior of using the anonymous
KProperty subclass for metadata
Initialization of companion object members (e.g., delegate properties
using provideDelegate convention) can depend on property metadata array,
which in turn can be initialized before other class members.

As of Kotlin 1.0 and 1.1, expression 'a in x .. y' is considered
equivalent to 'x.rangeTo(y).a', and should be evaluated in the following
order:
1. x
2. y
3. a
4. compare x with a
5. compare y with a (if needed)
It's safe to upcast integer types to Long,
floating-point types to Double.
So we don't have to create a range instance for cases such as
fun testLongInInt(x: Long, a: Int, b: Int) =
x in a .. b
which is equivalent to
fun testLongInInt(x: Long, a: Int, b: Int) =
x in a.toLong() .. b.toLong()
Provide BoundedValue-based implementation of InExpressionGenerator,
test it on range of comparable values.
Drop unneeded test (range of comparables is already tested by
ranges/contains/inComparableRanges.kt).
There's a subtle difference in behavior between comparing
primitive Float/Double (comparison follows IEEE standard)
and boxed Float/Double (comparison is a total order).
Make sure this corner case is preserved.
Reuse StringBuilder instances for nested subexpressions.
(NB StringBuilder instance for string template with a string
concatenation inside an expression entry, such as `"${"a" + "b"}"`,
will not be reused, although that doesn't seem to be a real-life issue).

Join adjacent strings literals, escaped strings, and constant values
(in a language version that supports const val inlining).
Use StringBuilder#append(char) for single-character constants
(e.g., " " in "$a $b").

Class.getMethod does not return protected methods from super class, so
we invoke getDeclaredMethod on each super class manually instead
