8272973: Incorrect compile command used by TestIllegalArrayCopyBeforeInfiniteLoop

[vieiro]

Backport of JDK-8272973.

Parity with 11.0.25-oracle.

Test passes in both release and fastdebug mode with private static final int iter = 10_000;

But with private static final int iter = 20_000; the test passes in release mode, but fails in fastdebug mode with assert(n->req() == 2 && n->in(1) != __null) failed: Only one data input expected:

# To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/cfgnode.cpp:621
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/home/avieirov/REPOS/OPENJDK/jdk11u-dev/src/hotspot/share/opto/cfgnode.cpp:621), pid=1641259, tid=1641275
#  assert(n->req() == 2 && n->in(1) != __null) failed: Only one data input expected
#
# JRE version: OpenJDK Runtime Environment (11.0.25) (fastdebug build 11.0.25-internal+0-adhoc.avieirov.jdk11u-dev)
# Java VM: OpenJDK 64-Bit Server VM (fastdebug 11.0.25-internal+0-adhoc.avieirov.jdk11u-dev, mixed mode, compressed oops, g1 gc, linux-amd64)
...

We may either:

1. Keep max iteration to 10_000, so at least this test runs (in both release and fastdebug modes) which seems to be the goal of 8272973.
2. Or try to first backport JDK-8312438 which in turn seems to be related to JDK-8263577 with seems to be a significant change 20297a1b

Please let me know preferred way to proceed.
