4736b317047ae6b04f7609843f21cb68fef6a0c1 LoongArch: gcc13: Implement option save/restore.
LTO option streaming and target attributes both require per-function
target configuration, which is achieved via option save/restore.
We implement TARGET_OPTION_{SAVE,RESTORE} to switch the la_target
context in addition to other automatically maintained option states
(via the "Save" option property in the .opt files).
