efda3aba10 Fast-ish path for drawing onto an image.RGBA destination.
Time to draw.Draw a 200x200 image fell from 18.4ms (and 1 malloc) to
5.6ms (and 0 mallocs). It's still relatively slow since it assumes
nothing about the src or mask images, but it does remove the malloc.
There are existing faster, more specialized paths for copies, fills
and image glyph masks.

Also added a "compare to a slow but obviously correct implementation"
check to draw_test.go.

b9caa4ac56 big: completed set of Int division routines & cleanups
- renamed Len -> BitLen, simplified implementation
- renamed old Div, Mod, DivMod -> Que, Rem, QuoRem
- implemented Div, Mod, DivMod (Euclidian definition, more
  useful in a mathematical context)
- fixed a bug in Exp (-0 was possible)
- added extra tests to check normalized results everywhere
- uniformly set Int.neg flag at the end of computations
- minor cosmetic cleanups
- ran all tests

Not sure what the other differences were for, but
they weren't working.

b3901dc1d8 Add _cgo_export.[ch] targets so that make knows how they are
built.  Note that they are only built if a //export comment
appears, so other targets should only use them if there is
such a comment.

Fixes #723.

3c32300c4d runtime: update godefs usage comment for GOARCH=386 GOOS={darwin,freebsd}
When trying to regenerate src/pkg/runtime/darwin/386/defs.h
on a 64 bit capable Snow Leopard (OS X 10.6.3) system I
needed to add -f -m32 to godefs, as this OS and hardware
combination defaults to 64 bit compilation.

For safety, make the same change to the 32 bit FreeBSD
instructions in .../freebsd/defs.c.  (Tested OK and no
problems introduced.)
