The generated code is more inline with java, and we avoid the error of
accessing package-private field outside of the package.
However, this changes semantics a bit. Now, a user should set assertion
status of inline-site's package, instead of inline function's one.

ASM has logic that splits exception tables in MethodWriter.computeAllFrames:
// Loop over all the basic blocks and visit the stack map frames that must be stored in the
// StackMapTable attribute. Also replace unreachable code with NOP* ATHROW, and remove it from
// exception handler ranges.
...
firstHandler = Handler.removeRange(firstHandler, basicBlock, nextBasicBlock);

#KT-28546 Fixed
Original problem is that lowered ir closures doesn't meet inliner expectations
about captured variable position in inlining method.
E.g.: Call 'foo(valueParam) { capturedParam }' to
inline function 'foo' with declaration
inline fun foo(valueParam: Foo, inlineParamWithCaptured: Bar.() ->) ....
is reorganized through inlining to equivalent call foo(valueParam, capturedParam1, cp2 ...).
But lowered closure for lambda parameter has totally different parameters order:
fun loweredLambda$x(extensionReceiver, captured1, cp2..., valueParam1, vp2...)
So before inlining lowered closure should be transformed to
fun loweredLambda$x(extensionReceiver, valueParam1, vp2..., captured1, cp2..)
#KT-28547 Fixed
In general case parameter type could differ from actual default lambda type.
E.g.: fun inlineFun(s: (Child) -> Base = { a: Base -> a as Child}),
where type of default lambda is '(Base) -> Child'.
In such case we should find somehow actual invoke method in bytecode knowing
only name, number of parameters and that's actual invoke is non-synthetic
regardless of bridge one.
#KT-21946 Fixed
Previously, inline suspend functions were effectively inline only,
but ordinary inline functions can be used as noinline.
To fix the issue, I generate two functions: one for inline with suffix
$$forInline and without state machine; and the other one without any
suffix and state machine for direct calls.
This change does not affect effectively inline only suspend functions,
i.e. functions with reified generics, annotated with @InlineOnly
annotation and functions with crossinline parameters.

Previously, assert was just a regular function and its argument used to
be computed on each call (even if assertions are disabled on JVM).
This change adds support for 3 new behaviours of assert:
* always-enable (independently from -ea on JVM)
* always-disable (independently from -ea JVM)
* runtime/jvm (compile the calls like javac generates assert-operator)
* legacy (leave current eager semantics) - this already existed
Default behaviour is legacy for now.
The behavior is changed based on -Xassertions flag.
#KT-7540: Fixed
Introduce COMMON_COROUTINES_TEST directive.
Every test with this directive is run twice: one time with
language version 1.2 and kotlin.coroutines.experimental package
and the other time with language version 1.3 and kotlin.coroutines
package. Each run is a separate method: with suffixes _1_2 and _1_3
respectively.
However, since codegen of release coroutines is not supported in JS
backend, we generate only one method: with suffix _1_2.
#KT-23362
Use fake continuation instead of ALOAD 0 while inlining
Do not generate state machine for inner lambdas and inner objects,
which capture crossinline suspend lambda.
