Fix up dump_printf_loc format attribute and adjust uses [PR106782]

As discussed on IRC, the r13-2299-g68c61c2daa1f bug only got missed
because dump_printf_loc had incorrect format attribute and therefore
almost no -Wformat=* checking was performed on it.
3, 0 are suitable for function with (whatever, whatever, const char *, va_list)
arguments, not for (whatever, whatever, const char *, ...), that one should
use 3, 4.

There are 3 spots where the mismatch was worse though, two using %u or %d
for unsigned HOST_WIDE_INT argument and one %T for enum argument (promoted
to int) and this backport just fixes those spots.
