Subject: [PATCH] Fix $mybool |=... which is binary op, not boolean op

# Fix $mybool |=... which is binary op, not boolean op

This fixes PhanTypeInvalidLeftOperandOfBitwiseOp.
Replace $var |= ... with $var = ... || $var .
Add cast before ... when needed (@include does not always return bool).
|= always evaluates expression, there for || $var, not $var ||
