        Description

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

        #
        # A fatal error has been detected by the Java Runtime Environment:
        #
        # SIGILL (0x4) at pc=0x0000ffff78202dcc, pid=2107437, tid=2107466
        #

        #
        # An error report file with more information is saved as:
        # /home/ninjia02/work/scratch/hs_err_pid2107437.log
        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.
