RFR(XS) 8227632: Incorrect PrintCompilation message: made not compilable on levels 0 1 2 3 4

[Boris Ulasevich]

Hi,

Can I please have a review for the simple logging issue. Current 
PrintCompilation message looks confusing, it reports "levels 0 1 2 3 4" 
when level 4 only was disabled.
Example:
$ echo [{ match: [\"*.*\"], c2: {Exclude:true} }] > cdf.txt
$ java -XX:+PrintCompilation -XX:+UnlockDiagnosticVMOptions 
-XX:CompilerDirectivesFile=cdf.txt HelloWorld
### Excluding compile: java.io.OutputStreamWriter::write
made not compilable on levels 0 1 2 3 4 
java.io.OutputStreamWriter::write (11 bytes) excluded by CompileCommand
### Excluding compile: java.lang.String::equals
made not compilable on level 0 1 2 3 4 java.lang.String::equals (50 
bytes)   excluded by CompileCommand
