Bug fixes and improvements of dialyzer_typesig
1. Sometimes the solver forgot that a list had entered the error state. The bug has been fixed by storing the atom 'error' in MapDict. An example where the bug occurred is io_lib_pretty:printable_bin(). The returned spec was weaker than it should have been, but the fix-point loop hid the bug (in this case). 2. lists:partition() has been substituted for lists:splitwith() in enumerate_constraints(). This fix together with 3. solves a problem with long execution times for deeply nested fun:s. An example which is now much faster is lib/compiler/test/lc_SUITE:deeply_nested/1 (included as dialyzer/test/small_SUITE_data/src/deep_lc.erl). 3. The calculation of components in enumerate_constraints() has been simplified and optimized. The important thing here is that _all_ of the simple constraints have been saturated before entering the complex part. 4. The pretty printing of constraints has been improved.
