Fix for g++ failure reported by Brendan.
* flow.c (find_basic_blocks): Delete check for in_libcall_block when
prev_code is a CALL_INSN. Change check for REG_RETVAL note to
use in_libcall_block.
(find_basic_blocks_1): Delete check for in_libcall_block when prev_code
is a CALL_INSN. If CALL_INSN and in_libcall_block, then change code
to INSN.
