fmt: format 0b, 0o prefixes in %#b and %O
This CL modifies fmt's printer to implement %#b and %O
to emit leading 0b and 0o prefixes on binary and octal.
(%#o is already taken and emits "0377"; %O emits "0o377".)
See golang.org/design/19308-number-literals for background.
For #19308.
For #12711.
Vet update is #29986.
