Pull in r195679 from upstream llvm trunk:
Don't use nopl in cpus that don't support it.
Patch by Mikulas Patocka. I added the test. I checked that for cpu names that
gas knows about, it also doesn't generate nopl.
The modified cpus:
i686 - there are i686-class CPUs that don't have nopl: Via c3, Transmeta
Crusoe, Microsoft VirtualBox - see
https://bbs.archlinux.org/viewtopic.php?pid=775414
k6, k6-2, k6-3, winchip-c6, winchip2 - these are 586-class CPUs
via c3 c3-2 - see https://bugs.archlinux.org/task/19733 as a proof that
Via c3 and c3-Nehemiah don't have nopl

Bad timespec_subtract() calculations produce negative tv_nsec on i386
which cause EINVAL returned from nanosleep() which cause loop in
cron_sleep() and making all cron jobs to start about 30 seconds earlier
(which cause f.e. logfiles rotation by newsyslog delayed by 1 hour).
Use simple and proved calculations from kernel's timespecsub() instead.

Fix the build so -DNO_TESTS is passed in various phases that don't
require tests in order to build or install. Crucially, don't try to
install tests during the lib32 install phase. This commit supersedes
r261081, which fixed the lib32 install phase problem, but didn't fix
other phases.

sh: Solve the alias recursion problem in a less hackish way.
Add the space to avoid alias recursion when the alias is expanded, not when
it is added.
As a result, displaying an alias via command -v, command -V or type no
longer erroneously appends a space. Adjust the tests so they now require
this bug to be absent.

dtrace: remove unexplained 16MB limitation from dt_alloc/dt_zalloc
The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
$ dtrace -x bufsize=17m -n ...
dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.

Fix 32-bit signal handling on ppc64. This was broken when the PSL_USERSTATIC
macro was changed. Since copying 64-bit srr1 into 32-bit srr1 drops the upper
32 bits, any bits set in the context were dropped, meaning the context check
fails. Since 32-bit set_context can't change those bits anyway, copy the ones
from the current context (td->td_frame) before calling set_context().

Mostly revert r260267 and hopefully really fix the original problem.
The latest draft of SBC-3 tells: "A MAXIMUM UNMAP LBA COUNT field set to
a non-zero value indicates the maximum number of LBAs that may be unmapped
by an UNMAP command." To me it does not sound like that limit is set per
single descriptor, but rather per all command. And I have at least one
device that behaves exactly that way. This patch fixes the problem there.

Ensure that the DMA delay does not get rounded down to zero ticks when
a timeout value of a single tick is given. With FreeBSD-10 and newer

Handle a VM-exit due to a NMI properly by vectoring to the host's NMI handler
via a software interrupt.
This is safe to do because the logical processor is already cognizant of the
NMI and further NMIs are blocked until the host's NMI handler executes "iret".
