Support JvmPackageName annotation in JVM back-end

Browse Source 
This annotation is currently internal because we only commit to its
support for our own libraries. It will be used to change JVM package
names of declarations in JDK-specific stdlib additions (now called
kotlin-stdlib-jre7/8), both to preserve source compatibility of the old
Kotlin code and to solve the split package problem (KT-19258)
