compiler: let initializers hold addresses of fields

    The runtime.dbgvars initializer looks like

    var dbgvars = []dbgVar{
            {"allocfreetrace", &debug.allocfreetrace},
    }

    Because the field address was not recognized as valid for a static
    initializer, the variable was initialized at runtime.  Normally that
    would be fine, but for the runtime package it meant that dbgvars was
    not initialized when it was read by parsedebugvars.  That meant that
    the GODEBUG environment variable did nothing.

    Fixing that revealed that the static initializer checks had to be more
    careful about interface types, just like the existing is_constant
    methods.

[ARM] Fix PR target/79239 - unrecognized insn after pragma gcc pop_options

{committed for rearnsha}

It turns out that because the compiler uses a hash table to save the
cl_target_option structures it is unsafe to modify the result of
build_target_option_node() (doing so will cause the hash lookup to
fail).  This PR was due to not properly understanding this limitation.

The fix is to create temporary copies of the cl_target_option nodes for
use during target option processing and then only creating the tree node
once the options have been suitably modified.

gcc:
        PR target/79239
        * arm.c (arm_option_override): Don't call build_target_option_node
        until after doing all option overrides.

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.

runtime: fix context used by getTraceback

    I typoed the argument passed to getcontext in getTraceback, and the
    error was hidden by ucontext_arg.  This would have been caught by some
    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
    running the libgo testsuite.  We should fix the libgo testsuite,
    somehow, so that they run.

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
             func (b *bufio.Reader) Buffered() int { // ERROR "non-local|redefinition"
                   ^
