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.

Treat them like lambdas. This means:
1) Like local suspend lambdas, which become "non-suspend" after creating
jvmSuspendView, they do this as well
2) They both are generated with the same codegen.
3) They are treated differently only on front-end side.
#KT-20364: Fixed
Sometimes instead of {POP, GETSTATIC Unit.INSTANCE, ARETURN} sequence
the codegen emits {CHECKCAST Unit, ARETURN} sequence, which breaks tail
call optimization. By replacing CHECKCAST with ARETURN we eliminate
this issue.
#KT-19790: Fixed
Before this change, the codegen used to generate beforeInlineMarker
in order to spill variables later. However, since the tailrec call
is replaced with jump, no afterInlineMarker is generated, leading to
inconsistency of these markers. Thus, the spilling fails.
This change disables generating of beforeInlineMarker.
#KT-21521: Fixed
Unlike ordinary lambdas suspend lambdas has create method which invokes
the constructor of the lambda object (continuation).
The inliner could not cope with this.
The previous change fixed the case of suspend lambda without receiver.
This change adds support of suspend lambdas with receiver.
#KT-21605: Fixed
in redundant locals elimination.
Since IgnoringCopySourceInterpreter ignores ALOADs and ASTOREs,
the source instruction of ALOAD K in {ALOAD N, ASTORE K, ALOAD K}
sequence is not ASTORE K. In this case we cannot simply replace K
with N, since there can be multiple {ALOAD N, ASTORE K} sequences
in separate branches. After replacement we get different stack
frames.
This change resolves this.
However, in ReturnUnitMethodTransformer we want to ignore copies
of the same GETSTATIC kotlin/Unit.INSTANCE, since we do not mess
with local variables and just replace ASTORE with ARETURN to help
tail-call optimization.
#KT-23373: Fixed
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.
#KT-19159: Fixed
Three modes:
- 'disable' (default): normalize constructor calls in coroutines only
(required because uninitialized objects can't be stored in fields),
don't insert additional code for forced class initialization;
- 'enable': normalize constructor calls,
don't insert additional code for forced class initialization;
- 'preserve-class-initialization': normalize constructor calls,
insert additional code for forced class initialization.
Jump out from expression (e.g., break or continue expression in call
arguments) requires stack normalization, which inserts POP instructions.
POPping an uninitialized value is similar to ASTORE, except that it
doesn't store a value to a local variable. Such POP instructions should
be removed during postprocessing of the uninitialized stores.
Use it for char boxing/unboxing and unit materialization.
Possible to use for other purposes, for example, to add type checks
to dynamics.

It's necessary for generic inline suspend as a codegen
for it uses binding slice SUSPEND_FUNCTION_TO_JVM_VIEW
to generate fake continuation parameter, so all the
descriptors that are used for body generation must be
obtained from the SUSPEND_FUNCTION_TO_JVM_VIEW
#KT-19528 Fixed
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
#KT-19475 Fixed
Dex ignores subsequent line numbers for same instructions and interprets
instruction after inline as if they were inlined. This makes debugger
behaves as if there's nowhere to stop on line with breakpoint.
This also makes stepping through inline function consistent with
non-inline analog. In both context debugger now stops on '}'.
#KT-18949 Fixed
#KT-17120 Fixed
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
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
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
