[Bug c/37881] -Wunreachable-code warns for system headers macros

[pinskia at gcc dot gnu dot org]

------- Comment #7 from pinskia at gcc dot gnu dot org  2008-10-27 01:49 -------
This requires us to record that the macros came from system headers and so did
the expansion.

Also -Wunreachable-code is useless for most cases in general because of
inlining and such.
