[Bug c++/15579] New: tree-ssa regression for C++ altivec tests

["janis187 at us dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Several of the C++ altivec tests (g++.dg/ext/altivec-[24568].C) fail
to compile since the tree-ssa merge when no optimization is used.  For
example, altivec-2.C gets the error "argument to `__builtin_altivec_dst'
must be a 2-bit unsigned literal".  In this case a literal '0' is turned
into a var_decl.  The same test is successful when compiled as C instead
of C++.
