CLANG_NO_IAS34 was introduced in r276696 to allow then-HEAD kernels to

a version of Clang with a sufficiently capable integrated assembler we
do not need the workaround any longer.

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.

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

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