Handle typeof_unqual, __typeof_unqual and __typeof_unqual__ keywords
using TYPEOF_KEYW token in the same way as typeof keyword.
Also ignore x86 __seg_fs and __seg_gs named address space qualifiers
using X86_SEG_KEYW token in the same way as const, volatile or
restrict qualifiers.
Fixes: ac053946f5c4 ("compiler.h: introduce TYPEOF_UNQUAL() macro")
Closes: https://lore.kernel.org/lkml/81a25a60-de78-43fb-b56a-131151e1c035@molgen.mpg.de/
