Fixed 6841800: Incorrect boundary values behavior for option -XX:MaxLabelRootDepth=0-6 leads to jvm crash

Problem:
MaxLabelRootDepth value less then 10 is invalid since
some required stubs will not be compiled.

Solution:
Assert if MaxLabelRootDepth is too small.
In product version set it to 100 if it < 100.
