fix binaryFun

1. Make binaryFun correct for integer comparison.
2. Remove import of half of phobos for 100% cases in phobos.

`sort`, `cmp`, `find`, `startsWith`,  `sum` and other algorithms would
be compiled faster.

Fix missing local import in std.math.expi.
move format to std.format

The reason is to do not import `std.uni` tables, `std.string` and
probably `std.algorithm`. Note that format is used in CTFE code and
`Exception` handing.

 And it is more comfortable to import `format` from `std.format`.
