JDK-8282797 - CompileCommand parsing errors should exit VM
Description
There's a typo in test runner. 
-XX:CompileCommand=compileony,compiler.codegen.Test8005033::testBitCount

Because of that, compiler directive fails.  It doesn't affect the testing functionality, but HotSpot has to compile all methods encountered.

After correcting the typo, hotspot only compiles the method it is supposed to test.  Test time of fastdebug build reduces from 16.778s to 0.226 

CompileCommand: An error occurred during parsing
Error: Unrecognized option 'compileony'
Line: 'compileony,compiler.codegen.Test8005033::testBitCount'

Usage: '-XX:CompileCommand=<option>,<method pattern>' - to set boolean option to true
Usage: '-XX:CompileCommand=<option>,<method pattern>,<value>'
Use:   '-XX:CompileCommand=help' for more information and to list all option.

> Why doesn't the compileCommand error cause a test failure? The complete runner is '-Xcomp -XX:CompileCommand=compileony,compiler.codegen.Test8005033::testBitCount' Even though the compiler directive misses, -Xcomp does compile all methods, including Test8005033::testBitCount (inlined by main). the other reason is that this bug has been fixed, so no exception will be thrown from this test.
