go/...: fix/disable broken tests

Browse Source 
gp/ssa: add {Start,Stop}TestLog methods to synthesized test main package.

go/ssa/interp: add (not thread-safe) intrinsics for atomic.Value,
which are now used by Getenv.

go/pointer: disable test of callbacks from runtime timers
as the analysis's intrinsics are out of date.  Also fix 3 typos.
