RFR (XS): 8222292: runtime/exceptionMsgs/ArrayIndexOutOfBoundsException/ArrayIndexOutOfBoundsExceptionTest.java timeout but test passed

[David Holmes]

Bug: https://bugs.openjdk.java.net/browse/JDK-8222292
webrev: http://cr.openjdk.java.net/~dholmes/8222292/webrev/ (diff also 
below)

The test is checking exception messages in three compilation modes using 
three @run directives:
- "normal" (start interpreted)
- C2 (via Xcomp 'no tiered')
- C1 (via Xcomp 'stop at level 1')

when the test is run with Graal enabled it doesn't make sense to run 
these three variants (i.e. Graal in C1/C2 mode is nonsensical - you get 
Graal with some flags that affect how Graal runs). It also turns out the 
"C1-Graal" variant takes 20+ minutes to execute so the test times out.

Simple fix: split the three tests into two distinct @test definitions. 
The first runs "normal" with or without Graal. The second runs C1/C2 
only when Graal is disabled. End result: we test four compiler variants, 
which is what we want. (Actually there is a fifth as we'll also test 
"normal" with Xcomp applied to it.)

Thanks,
David
