  OTP-16452    Application(s): compiler
               Related Id(s): ERL-1161

               Fixed a bug that could cause the compiler to reject
               valid code that used the is_map_key/2 BIF.


  OTP-16456    Application(s): compiler
               Related Id(s): ERL-1163

               Fixed a bug that could cause the compiler to reject
               valid code that matched the same map key several times.


  OTP-16466    Application(s): compiler
               Related Id(s): ERL-1170

               The compiler could crash when compiling a convoluted
               receive statement.


  OTP-16467    Application(s): compiler
               Related Id(s): ERL-1166, ERL-1167

               The compiler could crash when a fun was created but
               never used.

               The compiler could crash when compiling the expression
               true = 0 / X.
