libgo: add "vendor" to pkgpath for vendored standard packages

    Ensure that the packages vendored into the standard library do not
    have the same pkgpath as the actual packages.  If we don't, attempts
    to build and test the actual packages will get confused.  The specific
    error I was seeing was import loops, causing some of the packages to
    fail to get initialized, causing an obscure run time crash.

Fix bogus pr78886.c failure for avr

The test fails for avr because malloc has been declared to take
an unsigned long, whereas size_t for avr is only unsigned int.

Fixed by typedef'ing __SIZE_TYPE__ to size_t and using it in the
malloc function declaration.

compiler: report correct errors for sink methods

    If somebody writes

    func (s []int) _() {}

    we should report an error.  Before this patch we were silently
    accepting this code, because we didn't report any errors about the
    receiver if the method was a sink.

    This patch is unfortunately slightly complex to handle the case of

    func (x int) _() {}

    which we can only detect after define_global_names.
