The kbuild bot reported a build breakage with CONFIG_RETPOLINE=n
due to commit aaa5d90b395a ("net: use indirect call wrappers at
GRO network layer").
I screwed the wrapper implementation for such config.
Fix the issue properly ignoring the builtin symbols arguments,
when retpoline is not enabled.

This header define a bunch of helpers that allow avoiding the
retpoline overhead when calling builtin functions via function pointers.
It boils down to explicitly comparing the function pointers to
known builtin functions and eventually invoke directly the latter.

The macros defined here implement the boilerplate for the above schema
and will be used by the next patches.

rfc -&gt; v1:
 - use branch prediction hint, as suggested by Eric
v1  -&gt; v2:
 - list explicitly the builtin function names in INDIRECT_CALL_*(),
   as suggested by Ed Cree
