PR middle-end/48722
* emit-rtl.c (unshare_all_rtl_again): For CALL_INSNs,
reset_used_flags also in CALL_INSN_FUNCTION_USAGE.
(verify_rtl_sharing): Likewise and verify_rtx_sharing
in there too.
(unshare_all_rtl_in_chain): For CALL_INSNs
copy_rtx_if_shared also CALL_INSN_FUNCTION_USAGE.
* gcc.target/i386/pr48722.c: New test.
