replace copypasted ModuleLlvm::parse

[klensy]

replaced code same as in

rust/compiler/rustc_codegen_llvm/src/lib.rs

Lines 426 to 445 in bd36e69

	fn parse(
	cgcx: &CodegenContext<LlvmCodegenBackend>,
	name: &CStr,
	buffer: &[u8],
	dcx: DiagCtxtHandle<'_>,
	) -> Result<Self, FatalError> {
	unsafe {
	let llcx = llvm::LLVMRustContextCreate(cgcx.fewer_names);
	let llmod_raw = back::lto::parse_module(llcx, name, buffer, dcx)?;
	let tm_factory_config = TargetMachineFactoryConfig::new(cgcx, name.to_str().unwrap());
	let tm = match (cgcx.tm_factory)(tm_factory_config) {
	Ok(m) => m,
	Err(e) => {
	return Err(dcx.emit_almost_fatal(ParseTargetMachineConfig(e)));
	}
	};
	Ok(ModuleLlvm { llmod_raw, llcx, tm: ManuallyDrop::new(tm) })
	}
	}

except before error message was emitted via write::llvm_err, which returned other error kind, but it still ok?
