Spill stack for inline functions only if it's required

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.
