[PATCH 41/50] rtlanal.c:tls_referenced_p

[Richard Sandiford]

gcc/
        * rtl.h (tls_referenced_p): Take a const_rtx rather than an rtx.
        * rtlanal.c (tls_referenced_p_1): Delete.
        (tls_referenced_p): Take a const_rtx rather than an rtx.
        Use FOR_EACH_SUBRTX rather than for_each_rtx.
