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.

When we have some custom implementation of Comparable, it's important
that we compare values exactly as 'lowBound <= a && a <= highBound'.
Make sure that evaluation order and compareTo calls match for
optimized and non-optimized case.
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
#KT-18480 Fixed
The previous condition that checked if we'd skipped any optional
parameters didn't work when number of parameters > 32 because the number
of bit masks in that case was more than one
#KT-18404 Fixed
When a test is marked as ignored in JVM BE (i.e. IGNORE_BACKEND: JVM)
it's ignored in LightAnalysisModeTestGenerated. This means that
this tests is expected to fail. However, often tests that fail
in JVM blackbox tests, don't fail in LAMTG, therefore it's reasonable
to skip these tests in LAMTG at all.
The main reason is avoiding complicated operations like
dup + dup_x2 + pop2 for instances obtained by NEW instruction.
Otherwise it leads to problems in performRefinedTypeAnalysis
because code there has a sensible assumption that NEW instances
can be only dupped or stored into a local (rare cases)
#KT-17457 Fixed
Support Comparable#compareTo for boxed primitive in redundant
boxing/unboxing analysis, along with CHECKCAST to java.lang.Comparable.
Note that we can do that for Float and Double, too, because
Float#compareTo(Float) and Double#compareTo(Double) are delegated to
Float#compare(float, float) and Double#compare(double, double),
respectively.
Fuse specialized comparison for integers with conditional jumps
if possible (both for Comparable#compareTo and Intrinsics#areEqual).
#KT-11959 Fixed
These changes has been introduced in c3a032ea0b
to support new scheme for named functions
At the same time they can be avoided by generating some additional
code/accessors in the anonymous classes for coroutine state
Now we cannot simply remove introduced API because of bootstrap problems
#KT-17898 Fixed
In code like 'a?.b == 42', we can immediately generate equality
comparison result when receiver is null (false for '==', true for '!='),
since the primitive value is definitely non-null.
Otherwise unnecessary boxing/unboxing is generated to handle possibly
null result of 'a?.b'.
The problem was that the resume call (from doResume) for open members
was based on common INVOKEVIRTUAL to the original function
that lead to the invocation of the override when it was expected
to be the overridden (after super-call being suspended)
The solution is to generate method bodies for open members into
the special $suspendImpl synthetic function that may be called
from the doResume implementation
#KT-17587 Fixed
The main idea is to leave all the inline functions as is, without
state machines (but keeping suspend-calls markers) and
determine whether we need a state machine from the bytecode
after inlining into a non-inline function

Friend modules should be provided using the -Xfriend-modules flag
in the same format as -libraries. No manual configuration required for
JPS, Gradle and Maven plugins.
Friend modules could be switched off using the -Xfriend-modules-disabled
flag. Doing that will
* prevent internal declarations from being exported,
* values provided by -Xfriend-modules ignored,
* raise a compilation error on attemps to use internal declarations from other modules
Fixes #KT-15135 and #KT-16568.
NB: for-in-until loop is generated as precondition loop, because the
corresponding range is right-exclusive (and thus we have no problems
with integer overflows).
