Reordering `unsafe-vector-ref' past an `unsafe-vector-set!' was
particularly bad. Meanwhile, some non-mutating operations like
`unsafe-mcar' were treated too conservatively.

The FFI's weak table of callback procedures (to map Racket procedures
to FFI callback objects) suffered from the classic key-in-value
problem.

The bug was that a procedure could be incorrectly marked as
a "leaf" procedure, which could in turn cause the compiler
to keep inlining a very small procedure that calls itself.

Specifically, in the case that we're inheriting a language setting
from some earlier preference or something and the language we're
inheriting is one that saves prefixes, and the current file being
opened does not match any of the possible prefixes, then revert
to the not-a-language language, instead of using the value from
the preference
Also: finish the removal of the EoPL language level from the
DrRacket langauge dialog, and clean up the 'get guidance' dialog
Please cherrypick this commit to the 5.2 release branch
'read-language' uses as a single token in the case that read-language
fails. This helps it to deal with things like s-exp and at-exp
properly

This fix uses the same`run'-vs-`finishLaunch' technique as before,
but patches up the modal-dialog problem by calling `run' again
with a callback to start a modal loop.
Merge to 5.2.
I believe that this can go wrong in the case that you edit a buffer and switch tabs
before drracket fully finishes responding to the edited buffer (due to a queue-callback
that postpones some of the response to editing the buffer) for online expansion.
At least, this is how I guess that the error below happened:
send: target is not an object: #f for method: get-view
