[PATCH] IBM Z: Preserve exceptions in autovec-*-signaling-eq.c tests

[Ilya Leoshkevich]

DSE, DCE, and other passes are removing redundant signaling comparisons
from these tests, but the whole point is to check that GCC knows how to
emit them.  Use -fno-delete-dead-exceptions to prevent that.

gcc/testsuite/ChangeLog:

        * gcc.target/s390/zvector/autovec-double-signaling-eq.c:
        Preserve exceptions.
        * gcc.target/s390/zvector/autovec-float-signaling-eq.c:
        Likewise.
