64-bit systems.
Currently, there can be no more than INT_MAX positional parameters. Make
sure to treat all higher ones as unset to avoid incorrect results and
crashes.
On 64-bit systems, our atoi() takes the low 32 bits of the strtol() and
sign-extends them.
On 32-bit systems, the call to atoi() returned INT_MAX for too high values
and there is not enough address space for so many positional parameters, so
there was no issue.

Pull in r223171 from upstream llvm trunk (by Michael Zolotukhin):
PR21302. Vectorize only bottom-tested loops.
rdar://problem/18886083
This fixes a bug in the llvm vectorizer, which could sometimes cause
vectorized loops to perform an additional iteration, leading to possible
buffer overruns. Symptoms of this, which are usually segfaults, were
first noticed when building gcc ports, here:
https://lists.freebsd.org/pipermail/freebsd-ports/2014-September/095466.htmlhttps://lists.freebsd.org/pipermail/freebsd-toolchain/2014-September/001211.html
Since this fix is very important for ports, bump __FreeBSD_version to
make it easier for port maintainers to test whether the fix has been
applied.

When passing LUN IDs through treat ASCII values as fixed-length, not
interpreating NULLs as EOLs, but converting them to spaces.
SPC-4 does not tell that T10-based IDs should be NULL-terminated/padded.
And while it tells that it should include only ASCII chars (0x20-0x7F),
there are some USB sticks (SanDisk Ultra Fit), that have NULLs inside
the value. Treating NULLs as EOLs there made those LUN IDs non-unique.
The change to expand_number (r204654) broke detection of too large sizes and
relative sizes ('+'/'-').
Also add some tests.
The usr.bin/truncate/Makefile is slightly different in the MFC because

Move icl_pdu_get_data() and xpt_done() out of initiator's session lock.
During heavy reads data copying in icl_pdu_get_data() may consume large
percent of CPU time. Moving it out of the lock significantly reduces
lock hold time and respectively lock congestion on read operations.
