The dg-do directive appears after dg-require-effective-target in
g++.target/powerpc/pr106069.C.  That doesn't work the way that was
presumably intended.  Both of these directives set dg-do-what, but
dg-do does so fully and unconditionally, overriding any decisions
recorded there by earlier directives.  Reorder the directives more
canonically, so that both take effect.

Tested with gcc-13 targeting ppc64-vx7r2 on altivec-less hardware.  I'm
installing it as obvious, and backporting to the branches that have the
inconsistent testcase.
