- implemented setWord, use it where setUint64 is wrong
- divLarge: use fast mulWW, divWW; implemented mulWW, divWW
- better assembly code for addMulVVW

Previously the compiler would just emit "internal compiler error" when
trying to compute the remainder of floats or complex types.

Cached string indexing in inner loop of Btoui64.
Before:
strconv_test.BenchmarkAtoi 5000000 309 ns/op
strconv_test.BenchmarkAtoiNeg 5000000 325 ns/op
strconv_test.BenchmarkAtoi64 5000000 465 ns/op
strconv_test.BenchmarkAtoi64Neg 5000000 469 ns/op
After:
strconv_test.BenchmarkAtoi 10000000 182 ns/op
strconv_test.BenchmarkAtoiNeg 10000000 193 ns/op
strconv_test.BenchmarkAtoi64 10000000 251 ns/op

- support for binary prefix 0b (to match fmt.Format)
- renamed nat.new -> nat.setUint64 for consistency

Timings (as for change 1122043) go from 49ms to 48ms ish. It's
mostly lost in the noise, but it probably doesn't hurt.

To draw.Draw a 32x32 image.Alpha 10000 times,
Before: 633ms with 10000 mallocs
After: 49ms with 0 mallocs
These times are just blitting an image.Alpha, and do not include
rasterizing a glyph's vector contours to an image.Alpha.
The "generic" test case in draw_test.go tests this fast path.

- removed last argument (n) from all core arithmetic routines;
instead, use the length of the result
- simplified nat.make implementation and chose a better capacity
for new values, removed a TODO in the process
Changing the constant e from 1 (old) to 4 (new) improved
pidigits -s -n 10000 by ~9% (on a 3.06GHz Intel Core 2 Duo):
user 0m3.882s (old)
user 0m3.549s (new)

This permits cgo callbacks to work when run in init code.

- no need to make copies in cases of aliases
- removed deprecated internal shift functions
- minor unrelated simplifications
This change improves pidigits -s -n10000 by almost 20%:
user 0m6.156s (old)
user 0m4.999s (new)
(pidigits -s -n20000 goes from ~25s to ~19s)

Because maps are mostly a hidden type, they must be
implemented using reflection values and will not be as
efficient as arrays and slices.
