Don't measure wall time in map.go. Keep it portable
and only test NaN, but not time.
Move time tests to mapnan.go and only measure user CPU time,
not wall time. It builds on Darwin and Linux, the primary
platforms where people hack on the runtime & in particular
maps. The runtime is shared, though, so we don't need it to
run on all of the platforms.

The interpreter's os.Exit now triggers a special panic rather
than kill the test process. (It's semantically dubious, since
it will run deferred routines.) Interpret now returns its
exit code rather than calling os.Exit.
Also:
- disabled parts of a few $GOROOT/tests via os.Getenv("GOSSAINTERP").
- remove unnecessary 'slots' param to external functions; they
are never closures.
Most of the tests are disabled until go/types supports shifts.
They can be reenabled if you patch this workaround:

If the analysis reached a node twice, then the analysis was cut off.
However, if the second arrival is at a lower depth (closer to escaping)
then it is important to repeat the traversal.
The repeating must be cut off at some point to avoid the occasional
infinite recursion. This CL cuts it off as soon as possible while still
passing all tests.

The linker split PKGDEF into (prefix, name, def) pairs,
and defines def to begin after a space following the identifier.
This is totally wrong for the following export data:
func "".FunctionName()
var SomethingCompletelyUnrelated int

name=`"".FunctionName()\n\tvar`
def=`SomethingCompletelyUnrelated int`
since there is no space after FunctionName.
