Replace flow-control exception with explicit test.
It was noticed while profiling 'assets:precompile' in JRuby that
exception creation was consuming a large portion of time, and
some of that was due to File.atomic_write.
Testing first with File.exists? eliminates the need for an exception
which should be a perfomrance improvement on both JRuby and MRI.
In this case, the stat() isn't even extra overhead, since it is always
called.
