AVR: target/113156 - Fix ICE due to missing "Save" on -m[long-]double= options.
Multilib options -mdouble= and -mlong-double= are not orthogonal: TARGET_HANDLE_OPTION = avr-common.cc::avr_handle_option() sets them such that sizeof(double) <= sizeof(long double) is always true. gcc/ PR target/113156 * config/avr/avr.opt (-mdouble, -mlong-double): Add "Save" flag. (-mbranch-cost): Set "Optimization" flag.
