2b6cb317db Optmized decodeRefinement, moving the prediction error outside the inner loop 
There is no need to slow down the inner loop with a test for ltp as it can only
change if prediction is true in which case it only changes in the outer loop.

b3024db677 Estimate the size of decoded streams in advance. 
When decoding a stream, the decode buffer is often grown multiple times, its
byte size increasing like so: 512, 1024, 2048, etc. This patch estimates the
minimum size in advance (using the length of the encoded stream), often
allowing the smaller sizes to be skipped. It also renames numerous |length|
variables as |maybeLength| to make it clear that they can be |null|.

I measured this change on eight documents. This change reduces the cumulative
size of decode buffer allocations by 0--32%, with 10--20% being typical. This
reduces peak RSS by 10 or 20 MiB for several of them.

d0253c8291 Don't get bytes eagerly when creating {Jpeg,Jpx,Jbig2}Stream objects. 
This avoids lots of unnecessary work when such streams are referred to via
fetch(), and so their bytes aren't subsequently read. This is a large
performance win on some files.

f12d588258 Add an ensureRange() call to ChunkedStream_makeSubStream(). 
By checking if the data is all present before making a substream, we avoid
cases where we parse part of a stream and then throw a MissingDataException
part-way through, which forces us to later re-read the stream -- possibly
multiple times. This is a sizeable performance win for some cases when file
loading is slow (e.g. over the web).
