This breaks bootstrap on aarch64 (during stage2 build):
../../gcc/expmed.c: In function 'rtx_def* emit_store_flag_1(rtx, rtx_code, rtx,
rtx, machine_mode, int, int, machine_mode)':
../../gcc/expmed.c:5602:19: error: 'int_mode' may be used uninitialized in this
function [-Werror=maybe-uninitializ
While working on C++20 operator<=>, I noticed that build_new_op_1 was doing
too much conversion when a built-in candidate was selected; the standard
says it should only perform user-defined conversions, and then leave the
normal operator semantics to handle any standard conversions. This is
