Before:
  call ale#assert#SetUpLinterTest('vhdl', 'xvhdl')

After:
  call ale#assert#TearDownLinterTest()

Execute(The default xvhdl command should be correct):
  AssertLinter 'xvhdl', ale#Escape('xvhdl') . '  --2008 %t'

Execute(The xvhdl executable and options should be configurable):
  let b:ale_vhdl_xvhdl_executable = 'foobar'
  let b:ale_vhdl_xvhdl_options = '--something'

  AssertLinter 'foobar', ale#Escape('foobar') . '  --something %t'
