    Fix target/103910: missing GTY on x86_mfence causing PCH usage to ICE

    With -O3 -march=3Dopteron, a mfence builtin is added after the loop
    to say the nontemporal stores are no longer needed. This all good
    without precompiled headers as the function decl that is referneced
    by x86_mfence is referenced in another variable but with precompiled
    headers, x86_mfence is all messed up and the decl was GC'ed away.
    This fixes the problem by marking x86_mfence as GTY to save/restore
    during precompiled headers just like most other variables in
    the header file.

    Committed as obvious after a bootstrap/test on x86_64-linux-gnu.
