Alan Coopersmith 3eac9393d7 os: make FormatInt64() handle LONG_MIN correctly 
When compiling with gcc 15.2.0 using -O3 -m64 on Solaris SPARC & x64,
we'd get a test failure of:

Assertion failed: strcmp(logmsg, expected) == 0,
 file ../test/signal-logging.c, line 339, function logging_format

because 'num *= 1' produced a value that was out of the range of the
int64_t it was being stored in.  (Compiling with -O2 worked fine with
the same compiler/configuration/platform though.)
