[Pedro Franco de Carvalho]

As suggested in
https://sourceware.org/ml/gdb-patches/2018-10/msg00510.html, this
patch changes the documentation for the VSX tdesc feature to make it
clear that the altivec and FPU features are requirements.

YYYY-MM-DD Pedro Franco de Carvalho <***@linux.ibm.com>

* gdb.texinfo: Document the altivec and fpu requirements for
the org.gnu.gdb.power.vsx feature.

The only change is the last sentence, right?

The change is okay, but please include the name of the node in the
ChangeLog entry (in parentheses, as if it were the name of a
function).

Thanks.

I did also change "vector registers" to "vector-scalar registers" which
is the proper name for them. Sorry for the confusing diff, I
auto-formatted the paragraph.

Ok! I'll change it to "* gdb.texinfo (PowerPC Features):"
