xtensa: Enforce return address saving when -Og is specified

Leaf function often omits saving its return address to the stack slot,
and this feature often makes debugging very confusing, especially for
stack dump analysis.

gcc/ChangeLog:

* config/xtensa/xtensa.cc (xtensa_call_save_reg): Change to return
true if register A0 (return address register) when -Og is specified.
