4d12189b6c Build smbios.ko as a module for amd64 and i386
For whatever reason, smapi, smbios, vpd are all under the "bios" directory.
smapi is only for i386, so the entire "bios" directory is only built for
i386. Break smapi out, and make only it i386-specific. Then, build the
"bios" directory for both amd64 and i386.

9aca3e0f2b Clang's 3.5 integrated assembler now handles these files correctly (it
has support for the .codeXX directives). However, it is desirable, for
a time, to allow kernels to be built with clang 3.4. Historically, it
has been advantageous to allow stable X-1 to build kernels the old
way (so long as the impact of doing so is small), and this restores
that ability.

Also, centralize the addition of ${ASM_CFLAGS.${.IMPSRC}}, place it in
kern.mk rather than kern.pre.mk so that all modules can benefit, and
give the same treatment to CFLAGS in kern.mk as well.

2a8af197d4 Remove the clang -no-integrated-as workaround for smapi_bios.S, as clang
3.5.0 now supports the assembly just fine.

d0345bb310 Re-enable -Werror for these modules. It is already enabled for the same
files when built as part of a kernel.

07b202a847 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

2754fe609d Upgrade our copy of llvm/clang to r126079, from upstream's trunk.
This contains many improvements, primarily better C++ support, an
integrated assembler for x86 and support for -pg.

3258030144 Introduce the new kernel sub-tree x86 which should contain all the code
shared and generalized between our current amd64, i386 and pc98.

This is just an initial step that should lead to a more complete effort.
For the moment, a very simple porting of cpufreq modules, BIOS calls and
the whole MD specific ISA bus part is added to the sub-tree but ideally
a lot of code might be added and more shared support should grow.
