565b5dc076 gc: new typechecking rules
* 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.

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.
