Changes related to issue #731 method lookup regression.

[opeongo]

This is only a partial fix because each change uncovered another subtle issue. Still work to be done. I am posting this PR so that someone else who has a better idea of how this is supposed to work can at least see some of the issues that I found.

Fixing the issue for proper matching of the most specific method broke several other code paths that depended on the loose behaviour of the Types.castObject method. Other issues that popped up that I also fixed included:

• array dimensions occurring after a variable name being ignored (hidden problem that had not been tested yet).
• arrays of different dimensions but same base type being incorrectly matched as being cast compatible.
• Arrays of collections being cast to collections (surfaced by the change to Types.castObject, wasn't a problem before)

Unfortunately as I made changes more issues started to crop up and I just ran out of time. For example

• new {{false}, true}; no longer compiles and executes correctly. This looks to me like it shouldn't work anyway, because it is not a proper 2D array.
• entries = {{new Entry {"k"=3, "l"=5}, {6}}}; should get typed as Object[][][] but now is getting typed as 'MapEntry[][][]` and this fails. I suspect that I might have been going down the wrong track with some of my changes. Perhaps there is a simpler way to fix the original problem that does not cause so much other collateral damage.

I took another look and was able to fix the remaining issues, the fix just had to gestate. By the way new {{false}, true}; was explicitly test and checking the for an error, and my fix changed the error message (I think it made it better). Changing the expected error message fixed that part.

This PR should be ready to merge.
