runtime: fix setting of isarchive

    When I updated to Go 1.8, the initsig function moved from
    signal1_unix.go to signal_unix.go, and lost a gccgo-specific change in
    the move.  Add it back.

    This would have been caught by the misc/cgo/testcarchive tests in the
    gc repository, but we don't run those in the gccgo repository.  We
    should fix that, somehow.

    of the runtime package tests, but we don't run most of them because
    they rely on `go build`, and the go tool is not available while

compiler: improvements for type alias handling

    Give an error for an attempt to define a method on an imported type.

    Give an error for each attempt to define a method on a builtin type.

    Adjust error messages to be closer to gc error messages.

    With these changes gccgo passes current tests on dev.typealias branch.

    This changes the errors printed for test/fixedbugs/issue5089.go, but
    the change is an improvement:

        Before:
            fixedbugs/issue5089.go:13:1: error: redefinition of ‘bufio.Buffered’: receiver name changed
             func (b *bufio.Reader) Buffered() int { // ERROR "non-local|redefinition"
             ^
            fixedbugs/issue5089.go:11:13: note: previous definition of ‘bufio.Buffered’ was here
             import "bufio" // GCCGO_ERROR "previous"
                         ^

        Now:
            fixedbugs/issue5089.go:13:7: error: may not define methods on non-local type

re PR go/79037 (gccgo: Binaries crash with parforsetup: pos is not aligned on m68k)

PR go/79037
    compiler, runtime: align gc data for m68k

    The current GC requires that the gc data be aligned to at least a 4
    byte boundary, because it uses the lower two bits of the address for
    flags (see LOOP and PRECISE in runtime/mgc0.c).  As the gc data is
    stored as a [...]uintptr, that is normally always true.  However, on
    m68k, that only guarantees 2 byte alignment.  Fix it by forcing the
    alignment.

    The parfor code used by the current GC requires that the parfor data
    be aligned to at least an 8 byte boundary.  The code in parfor.c
    verifies this.  This is normally true, as the data uses uint64_t
    values, but, again, this must be enforced explicitly on m68k.

    Fixes GCC PR 79037.
