3f287b5002 big: implemented overlap-tolerant shifts in assembly 
- 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)

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

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.

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.)

- fixed a couple of bugs in the process
  (shift right was incorrect for negative numbers)
- added more tests and made some tests more robust

  by 2 instead of add

  This improves pidigit -s -n 10000 by approx. 5%:
