[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.

compiler: improvements for type alias handling
