[11u] RFR 8262295: C2: Out-of-Bounds Array Load from Clone Source

[Reingruber, Richard]

Hi,

Please help review this backport of JDK-8262295 to 11u.
The fix itself applies cleanly.
Just the test required trivial adaptation.
 
Original bug:
  https://bugs.openjdk.java.net/browse/JDK-8262295
  https://git.openjdk.java.net/jdk/commit/9689863a

11u webrev:
  http://cr.openjdk.java.net/~rrich/webrevs/8262295_11u_C2_Out_of_Bounds_Array_Load_from_Clone_Source/webrev.0/
 
Adaptations:

  I had to remove the package from the class ClassFileInstaller in the included
  test TestOutOfBoundsArrayLoad.java

Testing:

CI testing @SAP: JCK and JTREG, also in Xcomp mode, SPECjvm2008, SPECjbb2015, Renaissance Suite,
SAP specific tests with fastdebug and release builds on all platforms
 
Thanks, Richard.
