I've tested it on sparc64-linux if I remember right, there is -Av9a passed
to GAS automatically.
Anyway, -mvis should not turn -xarch=v9a, but v8plusa or v9a depending on
whether -m32 or -m64 (or what's the default).

This patch should take care of it, though I'm not able to test it on
Solaris (no access to it), will test it later on sparc*-linux.
While adding invoke.texi descriptions for -mvis and -mv8plus I took the
liberty of removing the descriptions of long time deprecated options, they
are deprecated since at least egcs 1.1.x and IMHO there is no need to even
tell anyone they exists still. I'll post a separate patch to remove them for
trunk.
