The trap builtin is target-specific. Making this system-specific (in

Is that necessary? Are there interesting targets that don't have a trap insn?
Depends on the definition of interesting.
I think avr, bpf, c6x, cr16, epiphany, fr30, frv, ft32, h8300, lm32, m32c,
m32r, mcore,
mmix, mn10300, moxie, msp430, or1k, pdp11, pru, rl78, rx, sh, stormy16, v850
and vax
don't have trap insn, while
aarch64, alpha, arc, arm, bfin, cris, csky, gcn, i386, ia64, iq2000, m68k,
microblaze,
mips, nds32, nios2, nvptx, pa, riscv, rs6000, s390, sparc, tilegx, tilepro,
visium and xtensa
have them.
