58e77990ba big: use fast shift routines 
- fixed a couple of bugs in the process
  (shift right was incorrect for negative numbers)
- added more tests and made some tests more robust
- changed pidigits back to using shifts to multiply
  by 2 instead of add

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

0b2e0265ae the android runner script 
this is a version synthesized from rsc's, dean's and my
	versions. changes and updates:

	- embeds the retval script and pushes a new version to the
          device if needed
	- passes arguments correctly to the program on the device
	- export GOARCH, GOTRACEBACK and GOGC from the local
          environment to the device.
	- added times.out support to run-arm

	enabled a few tests that are now passing and moved the
	GOGC=off workaround to run-arm.

5963dbac08 runtime: turn divide by zero, nil dereference into panics 
tested on linux/amd64, linux/386, linux/arm, darwin/amd64, darwin/386.
freebsd untested; will finish in a separate CL.

for now all the panics are errorStrings.
richer structures can be added as necessary
once the mechanism is shaked out.

ec53627ed5 runtime: correct memory leak in select 
* adds pass 3 to dequeue from channels eagerly

various other cleanup/churn:
  * use switch on cas->send in each pass to
    factor out common code.
  * longer goto labels, commented at target
  * be more agressive about can't happen:
    throw instead of print + cope.
  * use "select" instead of "selectgo" in errors
  * use printf for debug prints when possible
