Function and method calls are valid expression statements,
but calling certain built-in functions is not permitted.
Enumerate the built-ins.

Also: unsafe.Offsetof permits parenthesized selectors as
arguments.

This is simply documenting existing compiler behavior
(both gc and gccgo agree).

The change is a preparation for the new scheduler.
It introduces runtime.park() function,
that will atomically unlock the mutex and park the goroutine.
It will allow to remove the racy readyonstop flag
that is difficult to implement w/o the global scheduler mutex.

This proposal is a reformulation of CL 5987063. This CL resets
the default GOARM value to 6 and allows the use of the VFPv3
optimisation if GOARM=7. Binaries built with this CL in place
will abort if GOARM=7 was used and the target host does not
support VFPv3.

Both gc and gccgo permit calls such as unsafe.Sizeof(42). The
spec only permits variable arguments. This is a (backward-compatible)

restricting the compilers.
