Robert Griesemer b4be65bc7f math/big: simplify fast string conversion 
- use slice ops for convertWords instead of lo/hi boundaries
- always compute leading zeroes (simplifies logic significantly),
  but remove them once, at the end (since leafSize is small, the
  worst-case scenario is not adding significant overhead)
- various comment cleanups (specifically, replaced direct -> iterative,
  and indirect -> recursive)
- slightly faster overall for -bench=String

(This CL incorporates the changes re: my comments to CL 5418047
https://golang.org/cl/5418047/ )
