Subject: [PATCH] ignore compiler generated annotations during Kotlin live
 reload

instrument live-reload will compare class structure to make sure this class can be "redefine"
But the classes generated by Kotlin compiler contains debug annotations, the comparison always fail.

Exclude the annotations which generated by Kotlin compiler.
