[vector api] RFR: Fix jtreg vector reshape failures for AArch64 NEON

[Yang Zhang (Arm Technology China)]

Hi,

I have a patch which can fix jtreg (test/jdk/jdk/incubator/vector/VectorReshapeTests.java) test failures for AArch64 NEON.  Without this patch, test cases (testRebracket and testResize) will fail with the log "bad AD file".
Could you please help to review this?
