gdbserver: Clear X86_XSTATE_MPX bits in xcr0 on x32
I worried that there could be other paths that might result in an xcr0
value which has X86_XSTATE_MPX set in x32 mode. As everyone
eventually calls amd64_create_target_description to build their target
description, I figured we could assert in here that if X86_XSTATE_MPX
is set then we should not be an x32 target, this will uncover any
other bugs in this area.
I'm not currently able to build/run any x32 binaries, so I have no way
to test this, but the author of commit 4bb20a6244 did test this
series with that assert in place and didn't see any problems.
