Bug 567143 - fix broken comparison of bit masks

This method compares an expression of the form (e | C) to D. which will
always compare unequal due to the specific values of constants C and D.
This may indicate a logic error or typo.

Typically, this bug occurs because the code wants to perform a
membership test in a bit set, but uses the bitwise OR operator ("|")
instead of bitwise AND ("&").

Also such bug may appear in expressions like (e & A | B) == C which is
parsed like ((e & A) | B) == C while (e & (A | B)) == C was intended.
