Stack should be spilled before inline function call and restored after
call only if one of the following conditions is met:
- inline function is a suspend function
- inline function has try-catch blocks
- inline function has loops (backward jumps)
Note that there're quite some "simple" inline functions in Kotlin stdlib
besides run/let/with/apply. For example, many string operations are
implemented as inline wrappers over Java method calls.
Parse TryCatchBlockNode's in generated bytecode, infer stack save/restore points.
Save stack to local variables before 'try'.
Restore stack after the beginning of try-block, catch-block, and default handler.
Integrate before/after inline markers rewriting (otherwise it'll break our stacks).
#KT-3309 Fixed
Inlining code violates JIT assumptions for OSR in Java 8 in case of
starting with non-empty and containing cycles.
Fix is to mark each inlined block with markers and then store/restore
stack state before and after inlined body.
