The naked attribute is supported by at least gcc >= 4.6 (for ARM,
which is the only current user), gcc >= 8 (for x86), clang >= 3.1
and icc >= 13. See https://godbolt.org/z/350Dyc
Therefore, move it out of compiler-gcc.h so that the definition
is shared by all compilers.
This also fixes Clang support for ARM32 --- 815f0ddb346c
("include/linux/compiler*.h: make compiler-*.h mutually exclusive").
