Fix issue #1592 "LLVM code gen error when using a constant in an if"

Changes lb_build_if_stmt() to return null lbValue if condition is
  cmpAnd, cmpOr or non-const neg and check in lb_build_if_stmt()
  to avoid short circuiting if that's the case
Adds test to "tests/issues" and adds step in CI to check this dir
