The hard register A10 was already allocated for EH_RETURN_STACKADJ_RTX.
(although exception handling and sibling call may not apply at the same time,
but for safety)
gcc/ChangeLog:
* config/xtensa/xtensa.md: Change hard register number used in
the split patterns for indirect sibling call fixups from 10 to 11,
the last free one for the CALL0 ABI.
