ideally cause the compiler to give an error.  Right now 6g
warns about large shifts but does not give an error.  This CL
removes the out of range shift from shift.go, so that it will
work with gccgo, and adds a test case in bugs/ to be fixed at
a later date.

- leave only basic type conversions in that section
- we have a section of composite literals which covers those
- we have a section prepared (but not written) on type guards
- the built-in function "convert" doesn't need to be exposed
  as it is redundant

constant without an explicit conversion.  I think that is a
bug.  This adds a test case for it.

Also, change errchk to include the string BUG in error
messages, so that failures are included in the count reported
by the run shell script.
