[fpc-pascal] Multi helpers

[Ryan Joseph]

Update on multi-scope helpers. I’ve added tests (tmshlp*.pp), fixed a bug and renamed the mode switch to “multihelpers” which I think is more concise than “multiscopehelpers” and fits the format with “typehelpers”. Any better ideas are welcome of course.

I’ve made all the tests I could think of (included now) but I wonder if I messed up any subtle order of precedence. If anyone wants to test or has any ideas for more tests to include please let me know.
