regcomp.c: don't include INTERN.h

This file only needs including by globals.c; it was being included
in regcomp.c too as the declarations in regcomp.h aren't included by
perl.h and thus don't get pulled into globals.c.  This was a confusing
and hacky workaround.

Instead, this commit causes globals.c to #include regcomp.h directly

After this commit, only globals.c #includes INTERN.h
