The Vector API case IntMaxVectorLoadStoreTests fails on SVE system with SIGILL:

#
# A fatal error has been detected by the Java Runtime Environment:

Compiled method (c2) 2996 1079 ! 4 IntMaxVectorLoadStoreTests::loadArrayMaskIOOBE (177 bytes)

This SIGILL is triggered by assertion of verifying preserved p7 register being clobbered before returning to c2 compiled code.

P.S. The SIGILL comes from MacroAssembler::stop(), which should print meaningful message instead of a SIGILL.
