kasan: remove hwasan-kernel-mem-intrinsic-prefix=1 for clang-14
Some unknown -mllvm options (i.e. those starting with the letter "h")
don't cause an error to be returned by clang, so the cc-option helper adds
the unknown hwasan-kernel-mem-intrinsic-prefix=1 flag to CFLAGS with
compilers that are new enough for hwasan but too old for this option.
This causes a rather unreadable build failure:
fixdep: error opening file: scripts/mod/.empty.o.d: No such file or directory
make[4]: *** [/home/arnd/arm-soc/scripts/Makefile.build:252: scripts/mod/empty.o] Error 2
fixdep: error opening file: scripts/mod/.devicetable-offsets.s.d: No such file or directory
make[4]: *** [/home/arnd/arm-soc/scripts/Makefile.build:114: scripts/mod/devicetable-offsets.s] Error 2
Add a version check to only allow this option with clang-15, gcc-13
or later versions.
