We have recently added the predefined macro __S390_ARCH_LEVEL__ to
expand to a numerical value representing the architecture document
level currently in use. However, the IBM XL compiler already has a
macro named __ARCH__ for that purpose. So we change our macro to that
in order to improve portability.

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.
