* Code for assignment, conversions now mirrors spec.
* Changed some snprint -> smprint.
* Renamed runtime functions to separate
interface conversions from type assertions:
convT2I, assertI2T, etc.
* Correct checking of \U sequences.
Fixes#840.
Fixes#830.
Fixes#778.

(caused certain files to not be idempotent under gofmt)
- corrected golden files for go/printer
- slightly simplified some code in nodes.go (no impact on formatting)
- these changes have no impact on gofmt output of .go files under src, misc
fallthrough statement considered harmful!

Time (us) to draw a 200x200 src onto an image.RGBA dst with the Over
operator. Each case was measured three separate times, and the sorted
times are reported.
Fill case (where src is an image.ColorImage):
Before:
7438, 7511, 7526
After:
3073, 3087, 3102
Copy case (where src is an image.RGBA):
Before:
9506, 9510, 9563
After:
5262, 5300, 5344

Also fix an interface bug: white-space-delimited doesn't work well for cases like "%d, %d" on "23, 23")

charclass to avoid unnecessarily iterating over ranges.
Also, use the fact that IntVector is an []int to avoid method calls.
On my machine, this brings us from ~27500 ns/op to ~17500 ns/op in the benchmark I've added (it is also faster in the case where a range check
doesn't help, added a benchmark for this too.)
I'd also like to propose that "[]", and "[^]" be disallowed. They aren't useful as far as I can tell, they aren't widely supported, and they make reasoning about character classes a bit more complicated.

On error, ReadSlice is defined to return the available data
and advance past that data, but it was not behaving that
way for err == ErrBufferFull, making it harder for callers to
handle well.

- implement scanning for all renamed types
(compiler bug stops complex from being renamable,
so it can't be tested but the code is there)
- %q %x for strings
- error handling now done with panic/recover

For example, earlier, the regexp would accept SIGQUEUE_MAX
as a unix signal with name SIGQUEUE. Now it is ignored.

Also, move Do() to vector.go, so that Do() for IntVector and StringVector
is autogenerated.
The only files edited are Makefile, defs.go, and vector.go. The rest are
autogenerated with "make generate".

- reimplement integer scanning to handle renamed basic integer types
- start implementation of Fscanf and Scanf; not yet ready for general use.
This intermediate CL is a useful checkpoint. A similar change needs to be
done for float and complex, but it seemed worth getting the approach
reviewed before making those changes.

Fix Rectangle.Clip.
It could return a non-canonical rectangle if its arguments
did not overlap.
e.g. Rect(0, 0, 10, 10).Clip(Rect(0, 20, 10, 30)) -> Rect(0, 20, 10, 10)

ModInverse is just a small wrapper around GcdInt, but it's nice to
have in order to be clear about what one is doing in other code.
