Leonardo Duarte 335fae9a71 LibC: Return early in time_to_tm for large time_t 
POSIX says that localtime should fail with EOVERFLOW if the result
cannot be represented, which is the case for most large (in absolute
value) time_t inputs, since they overflow (or underflow) tm_year, which
is an int. This patch introduces this functionality. Previously, tm_year
just overflowed (or underflowed) silently.

Incidentally, this partially fixes #12729 without solving the root
problem, which is that time_to_tm is linear in its input to determine
the number of years since epoch.

This means that the bash port mktime test no longer times-out in 60s,
but it still fails (faster) in some other place. Due to underlying issue
in the algorithm, the worst case inputs still take a couple of seconds
on my machine.
