I went through suspicios %l in format strings of *printf family functions
combined with casts to (long) or (unsigned long) and tried to find out the
types of the original expressions that were cast.
Quite a few had size_t type, so I've used the new HOST_SIZE_T_PRINT_*
macros together with cast to fmt_size_t for those, and then there were
quite a few HOST_WIDE_INTs cast to long, used HOST_WIDE_INT_PRINT_* for
those without casts.  There was one case of a weird unsigned int variable
used with %lu and (long) cast too.
