Instead of sending events with an undefined id, we don't send them at

It doesn't need to have this logic.

ParseLazyFunctionLiteralBody is basically just ParseStatementList
+ log the function position. But PreParser doesn't need to have
the "which functions to log" logic, since logging the function is
always done exactly when Parser falls back to PreParser. (See
PreParseLazyFunction.)

So in the current state, PreParser would log several functions in
a SingletonLogger, and only the last one would take
effect (that's the one Parser also logs in SkipLazyFunctionBody).

Also updated test-parsing/Regress928 to produce the preparse data
the way we do now (i.e., not running the PreParser directly, but
running the Parser).

Error reporting: when PreParser finds an error, it doesn't need
to ReportUnexpectedToken in PreParseLazyFunction, since it
already has reported the error whenever it found it.

Now that all accesses to the last match info are in C++ and TF code, we can
finally turn the last match info into a FixedArray. Similar to the ArrayList,
it uses its first field to store its length and grows dynamically in amortized
O(1) time.

Unlike previously, this means that the last match info pointer stored on the
context can actually change (in case the FixedArray needs to grow).
