emit_trap removed

[SimonDanisch]

Seems like emit_trap got removed but is still being used? I'm using it too, so wondering if it was an accidant.

still in there:

GPUCompiler.jl/src/irgen.jl

Lines 284 to 292 in bc38cbb

	function emit_trap!(@nospecialize(job::CompilerJob), builder, mod, inst)
	trap_ft = LLVM.FunctionType(LLVM.VoidType())
	trap = if haskey(functions(mod), "llvm.trap")
	functions(mod)["llvm.trap"]
	else
	LLVM.Function(mod, "llvm.trap", trap_ft)
	end
	call!(builder, trap_ft, trap)
	end

this was a duplicate def

Ugh, I meant rm_trap! and somehow made emit_trap! out of it when I started looking at the PRs :D ...
And I guess rm_trap! is actually removed for good and unified with lower_unreachable_control_flow.
