    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.

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.
