RFR(M): 8007288: Additional WB API for compiler's testing

[Igor Ignatyev]

test 'compiler/whitebox/EnqueueMethodForCompilationTest' has failed 
during testing, because 'CompilationPolicy::can_be_compiled()' returns 
'true' for invalid comp_level (less that -1 or great that 4).

i added method 'is_compile' to check whether a value is valid level of 
compilation and rerun jprt.

in new results:
   - compiler/whitebox/IsMethodCompilableTest failed on on *-i586-*-c1 
due to JDK-8007270
   - timeouts in other compiler's tests:
     * compiler/6663848/Tester
     * compiler/6711100/Test
     * compiler/6792161/Test6792161
     * compiler/6863420/Test
     * compiler/6863420/Test
     * compiler/6901572/Test
     * compiler/7100757/Test7100757
     * compiler/7119644/TestFloatVect
     * compiler/7196199/Test7196199
     * compiler/7199742/Test7199742
