* common.opt (flag_sanitize_trap): New variable.
(fsanitize-trap=, fsanitize-trap): New options.
(fsanitize-undefined-trap-on-error): Change into deprecated alias
for -fsanitize-trap=all.
* opts.h (struct sanitizer_opts_s): Add can_trap member.
* opts.cc (finish_options): Complain about unsupported
-fsanitize-trap= options.
(sanitizer_opts): Add can_trap values to all entries.
(get_closest_sanitizer_option): Ignore -fsanitize-trap=
options which have can_trap false.
(parse_sanitizer_options): Add support for -fsanitize-trap=.
For -fsanitize-trap=all, enable
SANITIZE_UNDEFINED | SANITIZE_UNDEFINED_NONDEFAULT. Disallow
-fsanitize-trap=vptr here.
(common_handle_option): Handle OPT_fsanitize_trap_ and
OPT_fsanitize_trap.
* sanopt.cc (maybe_optimize_ubsan_null_ifn): Check
flag_sanitize_trap & SANITIZE_{NULL,ALIGNMENT} instead of
flag_sanitize_undefined_trap_on_error.
* gcc.cc (sanitize_spec_function): Use
flag_sanitize & ~flag_sanitize_trap instead of flag_sanitize
and drop use of flag_sanitize_undefined_trap_on_error in
"undefined" handling.
* ubsan.cc (ubsan_instrument_unreachable): Use
flag_sanitize_trap & SANITIZE_??? instead of
flag_sanitize_undefined_trap_on_error.
(ubsan_expand_bounds_ifn, ubsan_expand_null_ifn,
ubsan_expand_objsize_ifn, ubsan_expand_ptr_ifn,
ubsan_build_overflow_builtin, instrument_bool_enum_load,
ubsan_instrument_float_cast, instrument_nonnull_arg,

* varasm.cc (narrowing_initializer_constant_valid_p): Check
SCALAR_INT_MODE_P instead of INTEGRAL_MODE_P, also break on
! INTEGRAL_TYPE_P and do the same check also on op{0,1}'s type.

Narrow integer multiplication by a zero_one_valued_p operand.
(convert (cond @1 INTEGER_CST@2 INTEGER_CST@3)): Push integer
conversions inside COND_EXPR where both data operands are
integer constants.

* c-ubsan.cc (ubsan_instrument_division, ubsan_instrument_shift):
Use flag_sanitize_trap & SANITIZE_??? instead of
flag_sanitize_undefined_trap_on_error. If 2 sanitizers are involved
and flag_sanitize_trap differs for them, emit __builtin_trap only
for the comparison where trap is requested.
(ubsan_instrument_vla, ubsan_instrument_return): Use
lag_sanitize_trap & SANITIZE_??? instead of
flag_sanitize_undefined_trap_on_error.
