  [SDPatternMatch] Implement conditionally binding a value by using m_AllOf. NFC (#225559)

Making the predicate part of Value_bind has a non-zero code size and
compile time impact. I assume this is because the non conditional
m_Value needs a dummy predicate.

This patch removes the predicate from Value_bind and uses a m_AllOf so
we only pay for the predicate when we need it. This matches how this is
currently done in IR PatternMatch.
