The attached patch fixes a number of outstanding test failures
and ILP32-related bugs in the gimple-ssa-sprintf pattch pointed
out in bug 77676 and 77735).  The patch also fixes c_strlen to
correctly handle wide strings (previously it accepted them but
treated them as nul-terminated byte sequences), and adjusts the
handling of "%a" to avoid assuming a specific number of decimal
digits (this is likely a defect in C11 that I'm pursuing with

Tested on powerpc64le, i386, and x86_64.

There is one outstanding failure in the builtin-sprintf-warn-1.c
test on powerpc64le that looks like it might be due to the
printf_pointer_format target hook not having been set up entirely
correctly.  I'll look into that separately, along with pr77819.
