    gas: Don't skip SFrame FDE if .cfi_register specifies RA w/o tracking
    
    Do not skip SFrame FDE if .cfi_register specifies RA register without
    RA tracking being actually used. Without RA tracking the register
    contents can always be restored from the stack using the fixed
    RA offset from CFA.
    
    gas/
            * gen-sframe.c (sframe_xlate_do_register): Do not skip SFrame
            FDE if .cfi_register specifies RA register without RA tracking
            being used.
