Wrongly detects unreachable code

[lal12]

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Linux

What is the issue affecting?

Diagnostics/Syntax Checking, Hover

Expected Behaviour

Given the following code

local arr = {}

for k,v in pairs(arr) do
	if k == 1 then
		print("k == 1")
		error("hi", k, v)
	else
		error("hi", k, v)
	end
end

print("hello world")

print in the last line should not be marked as unreachable, since arr is empty and error is never called.

Actual Behaviour

print in the last line is marked as unreachable.

Reproduction steps

1. Open New Tab in VSCode
2. Paste code example from above
3. if not set automatically, change language to lua
4. see last line being greyed out

There is another case where it is wrongly detected:

function error()
	print("error")
end

if 1 == 1 then
	error()
else
	error()
end


print("hello world")

While in this case it is properly detected as being reachable:
