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.

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.

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.
