RFR(S): 8145345: LogCompilation output is empty after JEP165: Compiler Control

[Nils Eliasson]

Hi,

Please review this change that fixes log compilation. It changed the 
default value for the log option to the command line flag value in 
compilerDirectives.hpp, updates how CompileCommand=log updates the 
value, and adds a warning if per method logging is used but 
LogCompilation is not set.
