These lines of valid brightscript all produce parse errors:

m.isTrue = true = true
m.isTrue = m.isTrue = true
m.isTrue = m.isTrue = m.isTrue

However, wrapping each of them in parentheses removes the error.

  m.isTrue = (true = true)
  m.isTrue = (m.isTrue = true)
  m.isTrue = (m.isTrue = m.isTrue)

fix(parser): Allow complex expressions on RHS of set statements
506bb34 
The parser was a little bit too greedy when attempting to detect set
statements, which I should have noticed with the weird workarounds in
that function.  Now that we're _not_ trying to read an entire expression
as the left-hand side of a set statement (e.g.  `foo + bar *= 3`), that
complication can be removed.

Arbitrarily complex expressions are now supported on the right-hand side
of a set statement, e.g. `foo.bar = true and false or 3 > 4`
