Attached patch adds __builtin_iseqsig() to the middle-end and C family =
front-ends.
Testing does not currently check whether the signaling part works, =
because with optimisation is actually does not (preexisting compiler =
bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D106805)

Bootstrapped and regtested on x86_64-linux.
OK to commit?

(I=E2=80=99m not very skilled for middle-end hacking, so I=E2=80=99m =
sure there will be modifications to make.)
