Strengthen "insn" from rtx to rtx_insn * within the generated get_attr_
functions in insn-attrtab.c, without imposing a strengthening from rtx
to rtx_insn * on the param itself and thus the callers.
gcc/
* genattrtab.c (write_attr_get): Within the generated get_attr_
functions, rename param "insn" to "uncast_insn" and reintroduce
"insn" as an local rtx_insn * using a checked cast, so that "insn"
is an rtx_insn * within insn-attrtab.c
