Tighten up params of create_basic_block_structure
gcc/
* basic-block.h (create_basic_block_structure): Strengthen params
1 "head" and 2 "end" from rtx to rtx_insn *.
* cfgrtl.c (create_basic_block_structure): Likewise.
(rtl_create_basic_block): Update casts from void * to rtx to
rtx_insn *, so that we can pass them as rtx_insn * to
create_basic_block_structure.
* sel-sched-ir.c (sel_create_basic_block): Likewise.
