Added exact label names for labels
fix KT-5645: 'continue' inside 'do...while' statement works as goto to the beginning of the loop (not checking loop condition)

 #KT-5645 Fixed
Jump on 'continue' to condition entry points for all loops
Report 'break or continue outside a loop'
for break/continue outside a loop body (e.g. in loop condition)

 #KT-5724 Fixed
Fixed one part of 'Resolution error of this type shouldn't occur for...'

Result for "IF<T>(T, T)" can be "hasUnknownParameters"
if both arguments have types 'uninferred type parameter' (incomplete resolve case),
no constraints are added to the system.
Removed 'implicit this' from scope for member lookup
Added tests for KT-4870 "Change to constructor invocation" quick fix doesn't work

for local classes, objects and object expressions

 #KT-4870 Obsolete
Improved error message for 'nested class should be qualified'
Pseudocode: don't write full label name when jump on it
Fixed: label copies should be added to all labels
