Crashes on ppc/s390 after 8231441: AArch64: Initial SVE backend support

[Lindenmaier, Goetz]

Hi

Since that change was pushed, the vm crashes in the build:

To suppress the following error report, specify this argument
# after -XX: or in .hotspotrc:  SuppressErrorAt=/type.cpp:1022
#
# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (/usr/work/... /share/opto/type.cpp:1022), pid=28717, tid=28983

# No core dump will be written. Core dumps have been disabled. To enable core dumping, try "ulimit -c unlimited" before starting Java again

Do you have an ad-hoc idea of the problem?

I locally backed out the change which fixed the issue.

Best regards,
  Goetz.
