  -----------
  [Sema] Add a 'Semantic' parameter to Expr::isKnownToHaveBooleanValue

Some clients of this function want to know about any expression that is known
to produce a 0/1 value, and others care about expressions that are semantically
boolean.

This fixes a -Wswitch-bool regression I introduced in 8bfb353bb33c, pointed out
by Chris Hamilton!
