Pull in r180121 from upstream llvm trunk:
LoopVectorizer: Fix 15830. When scalarizing and unrolling stores make
sure that the order in which the elements are scalarized is the same
as the original order.
This fixes a miscompilation in FreeBSD's regex library.
This should fix lib/libc/regex/regcomp.c at -O3 with clang 3.3 r178860
on CPUs with SSE. Before this change, the vectorizer could incorrectly
rearrange the second loop in computejumps(), leading to possibly invalid
entries in the re_gets::charjump table.
The net result was that for example "sed s/@CC@/foo/" failed to work
correctly, leading to trouble with many configure scripts.
Return a lun count of 1 and a lun id of 0 when CAM attempts a REPORT_LUNS
command on a disk device. This quieseces some noise on the console that
recently appeared.
Teach the virtio block device to deal with direct as well as indirect
descriptors. Prior to this change the device would only work with guests
that chose to use indirect descriptors.
Modify the device reset callback to actually reset the device state.
Literally follow POSIX:
If the bs= expr operand is specified and no conversions other than sync,
noerror, or notrunc are requested, the data returned from each input
block shall be written as a separate output block.
In particular, when both bs=size and conv=sparce were specified, the
resulted file was fully filled, instead of sparce.

When doing RFC3042 limited transmit on the first on second
duplicate ACK make sure we actually have new data to send.
This prevents us from sending unneccessary pure ACKs.

Fix installkernel requiring users/groups defined in CHECK_UIDS
and CHECK_GIDS to exist since r152680. This is only needed for
installworld. The documented procedure of running mergemaster -p
to check for missing users is only needed for installworld, not
for installkernel. This fixes auditdistd incorrectly being
required for installkernel.
Add an option for the GE FES based packet engines. Its board IDs
overlap with the standard ones, so kernels for this family of boards

Problem has been reported and a solution discussed with vendor.

Prevent device.subr from auto-loading in the nameservers module.
This module doesn't need device support (but device.subr is loaded
indirectly through media/tcpip.subr which contains resolv stuff).
Partially uncommit r249779. The changes to share/common.subr were good
while the remaining changes were part of a much larger ``secret sauce''
involved in an up-coming commit that I'm still laboring on.
Partially implement generic_bs_*_8() for MIPS platforms.
This is known to work with TARGET_ARCH=mips64 with FreeBSD/BERI.
Assuming that other definitions in cpufunc.h are correct it will
work on non-o64 ABI systems except sibyte. On sibyte and o32 systems
generic_bs_*_8() will remain panic() implementations.
- Some BIOSes use an Extended IRQ resource descriptor in _PRS for a link
that uses non-ISA IRQs but use a plain IRQ resource in _CRS. However,
a non-ISA IRQ can't fit into a plain IRQ resource. If we encounter a
link like this, build the resource buffer from _PRS instead of _CRS.
- Set the correct size of the end tag in a resource buffer.

Fix two bugs when setting up a plip interface. First, dhcp status was not
being properly cleared each iteration of the loop. Second, values weren't
properly quoted when sent to the editor function.

Convert over the etherswitch framework to use VLAN IDs per port, rather
than VLAN groups.
Some chips (eg this rtl8366rb) has a VLAN group per port - you first
define a set of VLANs in a vlan group, then you assign a VLAN group
to a port.
Other chips (eg the AR8xxx switch chips) have a VLAN ID array per
port - there's no group per se, just a list of vlans that can be
configured.
So for now, the switch API will use the latter and rely on drivers
doing the heavy lifting if one wishes to use the VLAN group method.
Maybe later on both can be supported.

UI improvements. First, implement --default-item whenever and wherever
possible to save keystrokes. Second, overhaul startup/rcdelete for much
improved performance. Last, but not least, kill-off useage of --clear
and implement --keep-tite in harmony to minimize jarring transitions.
Also, fix local variable names where necessary while we're here with
other minor comment-enhancements/typo-corrections.
Add new flags `-d' (sets debug=1) and `-D file' (sets debugFile) and
improve debugging initialization. Also fixup USAGE statements while we're
here. Also, change initialization of main program to _not_ change working
directory, allowing the debugFile to be relative without confusion.
dup(2): Remove incorrect sentence about getdtablesize().
There are no getdtablesize() bounds on the file descriptor to be duplicated;
it only has to be open. If the RLIMIT_NOFILE rlimit was decreased after
opening the file descriptor, it may be greater than or equal to
getdtablesize() but still valid.

Enable libcompiler-rt on MIPS.
Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an
issue where __clzdi2 and __ctzdi2 would cause endless recursion. This
bug has been fixed in r230021 already, but for some reason we only
switched to libcompiler-rt on SPARC64 -- not MIPS.
This means we can finally use <stdatomic.h> on all our architectures.
