cmd/gofmt: normalize number prefixes and exponents
Rewrite non-decimal number prefixes to always use a lower-case base
("0X" -> "0x", etc.), and rewrite exponents to use a lower-case 'e'
or 'p'. Leave hexadecimal digits and 0-octals alone.
Comparing the best time of 3 runs of `time go test -run All` with
the time for a gofmt that doesn't do the rewrite shows no increase
in runtime for this bulk gofmt application (in fact on my machine
I see a small decline, probably due to cache effects).
