The g++.dg/cpp1y/vla-initlist1.C test relies on undefined behavior

The attached patch removes the undefined behavior while still
verifying the same thing. It passes on powerpc64le.
Jason, based on your comment in the bug I've removed the part
of the test that verifies that the no-op initializer-list ctor
for the user-defined VLA leaves the array elements uninitialized.
If that's something that should be tested let me know and I'll
add another test or test case for that.
Actually, yes, the testcase is testing for that as well. Is that the
part that breaks on PPC64LE?
