r152494 added the recording of lineStart values for divot positions.
This is needed for the computation of column numbers. Similarly, it also
added the recording of line numbers for the divot positions. One problem
with the approach taken was that the line and lineStart values were
recorded independently, and hence were not always guaranteed to be
sampled at the same place that the divot position is recorded. This
resulted in potential mismatches that cause some assertions to fail.

The solution is to introduce a JSTextPosition abstraction that records
the divot position, line, and lineStart as a single quantity. Wherever
we record the divot position as an unsigned int previously, we now record
its JSTextPosition which captures all 3 values in one go. This ensures
that the captured line and lineStart will always match the captured divot
position.

Source/JavaScriptCore:

The most relevant change is in handlerForBytecodeOffset(), which fixes the inequality
used for checking whether a handler is pertinent to the current instruction. '<' is
correct, but '<=' isn't, since the 'end' is not inclusive.

Also found, and addressed, a benign goof in how the finally inliner works: sometimes
we will have end > start. This falls out naturally from how the inliner works and how
we pop scopes in the bytecompiler, but it's sufficiently surprising that, to avoid any
future confusion, I added a comment and some code to prune those handlers out. Because
of how the handler resolution works, these handlers would have been skipped anyway.

Also made various fixes to debugging code, which was necessary for tracking this down.
