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.

PR target/113156
* config/avr/avr.opt (-mdouble, -mlong-double): Add "Save"
flag.
(-mbranch-cost): Set "Optimization" flag.
