    Fix PR target/96607

    After 15 years trying to find out what can go into the delay slot of
    the call to __tls_get_addr with the Solaris linker, it's now time to
    concede defeat and consider it as not to be filled.

    gcc/ChangeLog:
            PR target/96607
            * config/sparc/sparc-protos.h (eligible_for_call_delay): Delete.
            * config/sparc/sparc.c (eligible_for_call_delay): Likewise.
            * config/sparc/sparc.md (in_call_delay): Likewise.
            (tls_delay_slot): New attribute.
            (define_delay [call]): Use in_branch_delay.
            (tgd_call<P:mode>): Set type to call_no_delay_slot when
            tls_delay_slot is false.
            (tldm_call<P:mode>): Likewise.=
