[CLEANUP] Mark locally-used functions static

Hi everyone,

This patch marks "static" a bunch of locally-used, non-debug functions
within the GCC sources.  Doing so addresses a subset of the warnings emitted
when compiling the GCC sources with -Wmissing-declarations.

I bootstrapped and regtested this change on x86_64-unknown-linux-gnu.

Please CC Fortran@ for Fortran FE patches.
Functions in the Fortran FE should lose their gfc_ prefix upon being made 
static.

Thanks,

The gcc/ parts are ok.

It seems this hasn't been committed.  I just re-discovered that
gcc/omp-low.c:simd_clone_vector_of_formal_parm_types could/should be
static but isn't.  Instead of now resolving that one individually:
Patrick, are you going to resolve the whole lot (in next stage 1, I
suppose)?
