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.

{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.

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.
