This change reverts most of r281985.
The method did not map to anything defined by SMBus protocol and could
not be implemented for SMBus controllers.
This change is obviously not backwards compatible, but I have good
reasons to believe that there have never been any users of SMB_TRANS.

Running `make libfoo.ll` or `make libfoo.bc` within a library directory
will now give us an LLVM IR version of the library, and `make foo.full.ll`
or `make foo.full.bc` will give us an IR version of a binary.
As part of this change, we add an LLVM_LINK variable to sys.mk that can be
specified/overridden using an external toolchain.

Summary:
The hardware does not expose a classic SMBus interface.
Instead it has a lower level interface that can express a far richer
I2C protocol than what smbus offers. However, the interface does not
provide a way to explicitly generate the I2C stop and start conditions.
It's only possible to request that the stop condition is generated
after transferring the next byte in either direction. So, at least
one data byte must always be transferred.
Thus, some I2C sequences are impossible to generate, e.g., an equivalent
of smbus quick command (<start>-<slave addr>-<r/w bit>-<stop>).
At the same time isl(4) and cyapa(4) are moved to iicbus and now they use
iicbus_transfer for communication. Previously they used smbus_trans()
interface that is not defined by the SMBus protocol and was implemented
only by ig4(4). In fact, that interface was impossible to implement
for the typical SMBus controllers like intpm(4) or ichsmb(4) where
a type of the SMBus command must be programmed.
The plan is to remove smbus_trans() and all its uses.
As an aside, the smbus_trans() method deviates from the standard,
but perhaps backwards, FreeBSD convention of using 8-bit slave
addresses (shifted by 1 bit to the left). The method expects
7-bit addresses.
There is a user facing consequence of this change.
A user must now provide device hints for isl and cyapa that specify an iicbus to use
and a slave address on it.
On Chromebook hardware where isl and cyapa devices are commonly found
it is also possible to use a new chromebook_platform(4) driver that
automatically configures isl and cyapa devices. There is no need to
provide the device hints in that case,
Right now smbus(4) driver tries to discover all slaves on the bus.
That is very dangerous. Fortunately, the probing code uses smbus_trans()
to do its job, so it is really enabled for ig4 only.
The plan is to remove that auto-probing code and smbus_trans().

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 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.

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.

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".
These two ALU instructions first appeared on Linux. Then, libpcap adopted
and made them available since 1.6.2. Now more platforms including NetBSD
have them in kernel. So do we.
--이 줄 이하는 자동으로 제거됩니다--
As a foundation for future work with LLVM's Intermediate Representation (IR),
add new suffix rules that can be used to build .llo (text) or .bco (bitcode)
files from C or C++ sources. This compilation step uses the same CFLAGS, etc.,
as are used for building .o files, with the exception of optimization flags.
Many of the things we would like to do with IR (e.g., instrumentation) work
better with unoptimized code, so our approach is to build .c->.bco without
optimization and then apply the optimization in post-analysis,
post-instrumentation linking.
The overall result of these changes is:
* one can "make foo.llo" or "make foo.bco" wherever "make foo.o" was supported
* new make variables IR_CFLAGS and IR_CXXFLAGS are available to inspect the
flags that are used by Clang to generate the IR
These new rules are added unconditionally to our non-POSIX suffix rule set,
since we cannot inspect COMPILER_TYPE in sys.mk. Future changes that depend
on these rules (e.g., building IR versions of binaries from bsd.prog.mk)
should use COMPILER_TYPE to determine when we can expect IR rules to succeed.

Refactor make suffix rules into separate files (one for POSIX and one not),
and rationalise the rules so that bsd.lib.mk can contain only those rules
that are library-specific (.c.po and .c.pico).
This can be accomplished by adding ${STATIC_CFLAGS} to the .c.o rule
unconditionally. STATIC_CFLAGS are only defined for use by sys.mk rules in
lib/libpam/Makefile.inc (see r227797), so it should be safe to include
them unconditionally in sys.mk's .c.o rule (tested by make universe and a
ports exp-run).
