    Go 1.8 includes a language change (https://golang.org/doc/go1.8#language):
    in an explicit conversion from one struct type to another, any field
    tags are ignored.
    
    This CL implements this language change in the gofrontend.  The tests
    for this are in the gc testsuite, which will be copied into the gccgo
    repository in due course.
    
    Updates golang/go#16085.

Add an assert to leaf_function_p to ensure it is not called from a
prolog or epilog sequence (which would incorrectly return true in a
non-leaf function).  There are several targets which still call
leaf_function_p, and while most appear safe or appear aware of the
issue, it is likely not all such calls are safe.  This check enables
any such latent bugs to be found.

    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.
