In r307676, several make rules were added for LLVM IR files, both in
text and binary format. Unfortunately these use different suffixes from
what upstream uses:
* Text IR has upstream suffix ".ll", while r307676 uses ".llo"
* Binary IR has upstream suffix ".bc", while r307676 uses ".bco"
Change these to what upstream uses instead.

The mode of operation (elfcopy, mcs, or strip) is chosen based on the
program name. Broaden this to allow a substring match at the end of the
name to allow prefixes - for example, bsdstrip or aarch64-freebsd-strip.
This improves use of these tools as drop-in replacements for GNU objcopy
and strip, which are often built with a limited set of supported targets
and installed with a target prefix for cross tools.

The driver currently supports chips that are fully compliant with the
JEDEC SPD / EEPROM / TS standard (JEDEC Standard 21-C,
TSE2002 Specification, frequenlty referred to as JEDEC JC 42.4).
Additionally some chips from STMicroelectronics are supported as well.
They are compliant except for their Device ID pattern.
Given the continued lack of any common sensor infrastructure, the driver
uses an ad-hoc sysctl to report the temperature.

If the device tree doesn't contain a cpu-handle field in any bman-portal or
qman-portal, it will exit without setting up the devinfo, leaving it
uninitialized. This will lead to attempts to free random memory, and ultimately
panic.
Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement. setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).
Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.
Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.
Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used. However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.
Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI. Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.

libc++'s stddef.h includes an existing definition of max_align_t for
C++11, but it is only defined for C++, not for C. In addition, GCC and
clang both define an alternate version of max_align_t that uses a
union of multiple types rather than a plain long double as in libc++.
This adds a __max_align_t to <sys/_types.h> that matches the GCC and
clang definition that is mapped to max_align_t in <stddef.h>.

Currently, '/etc/rc.d/swaplate stop' removes all swap devices. This can be
very slow and may not even be possible if there is a lot of swap space in
use. However, removing swap devices is only needed for late swap devices
that may depend on daemons that subsequent shutdown steps stop. Normal swap
devices such as hard disk partitions will remain available throughout the
shutdown process and need not be removed.
In swapoff, interpret -aL to remove late swap devices only, and use this in
etc/rc.d/swaplate. The meaning of -aL in swapon remains unchanged (add all
swap devices, both normal and late).

after r307676, which added transformation rules for .llo and .bco files.
These suffixes also have to be added the the global .SUFFIXES target,
otherwise the various suffix-transformation rules would be interpreted
as literal targets. E.g.,
.c.bco:
... commands ...
would actually to build a file named ".c.bco".
In r307684, I changed rescan_or_reset_bus() to bzero stack-allocated CCBs
before sending them to the kernel because there was stack garbage in there
that wound up meaning that bogus CCB flags were set.
While this fixed the 'camcontrol rescan all' case (XPT_DEV_MATCH CCBs were
failing previously), it broke the 'camcontrol rescan 0' (or any other
number) case when INVARIANTS are turned on. Rescanning a single bus
reliably produced an assert in cam_periph_runccb():
panic: cam_periph_runccb: ccb=0xfffff80044ffe000, func_code=0x708, flags=0xffffdde0
The flags values don't make sense from the code. Changing the CCBs in
rescan_or_reset_bus() from stack to heap allocated avoids the problem.
It would be better to understand why userland stack allocated CCBs don't
work properly, since there may be other code that breaks if stack allocated
CCBs don't work.
sbin/camcontrol/camcontrol.c:
In rescan_or_reset_bus(), allocate the CCBs using malloc(3) instead
of on the stack to avoid an assertion in cam_periph_runccb().

In sendit(), if mp->msg_control is present, then in sockargs() we are
allocating mbuf to store mp->msg_control. Later in kern_sendit(), call
to getsock_cap(), will check validity of file pointer passed, if this
fails EBADF is returned but mbuf allocated in sockargs() is not freed.
Made code changes to free the same.
Since freeing control mbuf in sendit() after checking (control != NULL)
may lead to double freeing of control mbuf in sendit(), we can free
control mbuf in kern_sendit() if there are any errors in the routine.
