Make enum entries initialize before companion object. This helps
in situation when companion object initializer refers to enum fields.
JVM be generates <clinit> method which first initializes all enum fields
and then runs companion object initializer. This commit introduces the
similar behaviour in JS BE. The old behaviour was: initialize companion
object in constructor. In enum, constructor is called to initialize
enum fields, so previously companion object was initialized first,
which is incorrect.

The <Type>Array.iterator used to lack next<Type>() method (KT-16626).
The -Xtypedarray compiler key enables translation of primitive arrays
to TypedArrays, and primitive array`is`-checks (KT-15358, KT-14007,
KT-14614, KT-16056).
Allow the compiler to read such libraries without any errors, at the
risk of crashing with an exception.
Also fix a minor bug in the diagnostic message in LibrarySourcesConfig
and in the corresponding test in KotlinJpsBuildTest
Inject LanguageVersionSettings instead; all information relevant to the
analysis should be now passed via an instance of LanguageVersionSettings
(which should be renamed to a more general name in the future).
This is partially a revert of d499998 and related commits
This makes it possible to drop CompilerConfiguration from
CallCheckerContext, which in turn helps to avoid passing the entire
CompilerConfiguration instance through front-end
Allow kotlin.jvm.internal.Intrinsics#areEqual for boxed values.
Rewrite to primitive equality.
NB we can't do that for Float and Double, because java.lang.Float#equals
and java.lang.Double#equals behave differently from primitive equality comparisons.
KT-16194 Code with unnecessary safe call contains redundant boxing/unboxing for primitive values
KT-12839 Two null checks are generated when manually null checking platform type
Recognize some additional cases of trivial null checks and trivial instance-of checks.
A variable is "checked for null", if it is:
- a function parameter checked with 'INVOKESTATIC kotlin/jvm/internal/Intrinsics.checkParameterIsNotNull'
- checked for nullability with 'IFNULL/IFNONNULL'
- checked for nullability with 'INSTANCEOF'
(if objectref is instance-of T, then objectref is non-null)
Before analyzing nullability, introduce synthetic assumptions for execution branches
where a variable is guaranteed to be null or not null. For example, the following bytecode:
ALOAD 1 // Ljava/lang/String;
IFNULL L
<non-null branch>
L:
<null branch>
is transformed to
ALOAD 1
IFNULL L1
NEW java/lang/String
ASTORE 1 // tells analyzer that variable 1 is non-null
<non-null branch>
L:
<null branch>
L1:
ACONST_NULL
ASTORE 1 // tells analyzer that variable 1 is null
GOTO L
After the analysis is performed on a preprocessed method,
remember the results for "interesting" instructions
and revert the preprocessing transformations.
After that, perform bytecode transformations as usual.
Do not transform INSTANCEOF to-be-reified, because reification at call site
can introduce null checks. E.g.,
inline fun <reified T> isNullable() = null is T
...
assert(isNullable<String?>())
The problem is very subtle (see the test): when generating a signature
for an object literal we also were mapping its super-class
(a type alias here).
Although we did unwrap its underlying constructor to map it properly
we did too late (after obtaining value parameters from the type alias constructor descriptor).
Another problem is that TypeAliasConstructorDescriptor.getOriginal
in the case does return itself, while it's expected to return
unsubstituted version
Note: everything works for common calls for such constructors
because they mapped through mapCallableMethod which contains
another custom unwrapping of type alias constructors
#KT-16555 Fixed
(it can be different from 'getContainingDeclaration()' in case of type alias constructor).

1. Analyze method node with fake jumps for loops to make sure that
all instructions reachable only through break/continue jumps are processed.
2. Fix stack for break/continue jumps.
3. Drop fake jumps for loops, analyze method node again.
4. Fix stack for try/catch and beforeInline.
Instead of requiring to pass it in SerializerExtensionBase's
constructor, pass it always in serializePackage. This is more
straightforward and helps in a situation where one SerializerExtension
instance is used for the whole module, not one per-package
