[Bug c++/28113] New: vectors initialized in ctors, not at compile time, cause altivec-3.C failure

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Test g++.dg/ext/altivec-3.C has been failing for mainline on powerpc64-linux
systems without VMX hardware since this patch, a fix for PR20103, was added:

The test calls a function at runtime to determine if VMX hardware is available
and if not, skips the rest of the test.  It now fails because vector global
variables are initialized by constructors instead of at compile time.  Here's a
minimal example:

  __vector signed int vsi = (__vector signed int) {40, 41, 42, 43};
  int main () { return 0; }

If the new behavior is expected then I'll change the test to be compile-only on
systems without VMX hardware.
