Title: in {zeros,ones}_like, don't insert fill for scalar.

This make the graph before compilation and when compiled with
FAST_COMPILE more readable. This was optimized away to
local_fill_to_alloc, but if we enable it in fast_compile, it also do
more optimisation that make the graph not readable without enabling even
more optimization in fast_compile.s
