LibC: Fix inttypes.h macros for x86-64 and extend them

On x86-64, `int64_t` is defined to be `long` (not `long long`) , so for
printing, the "l" format specifier has to be used instead of i686's
"ll".

A couple of these macros weren't updated when the x86-64 target was
added, so using them produced warnings like this:

> warning: format specifies type 'long long' but the argument has type
> 'int64_t' (aka 'long') [-Wformat]
>
>       "DW_CFA_GNU_negative_offset_extended(%" PRId64 ")\n", offset);
>       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~

This commit changes the macros to be correct for both architectures, and
reorders them to be consistent and adds a couple missing ones for the
sake of completeness.
