Stop including cidmaps.js
...
In b5b94a4af3
, i.e. PR #4259 , we stopped using cidmaps.js. Despite that, it's still included when PDF.js is built. At almost 0.5 MB (and approx. 7000 lines), this is currently the single largest file in the codebase.
Including such a large file in the builds, when it is not actually used, seems extremely wasteful; hence this patch.

I have a large PDF where this function is called 1.6 million times

cumulative allocations done by Firefox within this function from 113 MB
to 48 MB.

[CIDFontType2] Map characters missing in toUnicode to the private use area (bug 1028735 and issue 4881)

Improve how DecodeStream handles empty buffers.
...
DecodeStream currently initializes its |buffer| field to |null|, which
is reasonable, because lots of DecodeStreams never need to instantiate a
buffer. But this requires various special cases in the code.
This patch change it so DecodeStreamClosure has a single empty
Uint8Array which gets shared between all buffers upon initialization.
This avoids the special cases.
DecodeStream.prototype.ensureBuffer() is really hot, and this removes a
test from the fast path. For one 226 page scanned document this sped up
rendering by about 2%.

this: 'R1.0'. This conversion is repeated numerous times.
This patch factors out the conversion into a new function.

Avoid allocating return object in EvaluatorPreprocessor_read().
...
This function can be called 100s of 1000s or even millions of times, and the
allocated return object accounts for 10% of all GC thing allocations for some
documents. It's easy to avoid, which reduces stress on the garbage collector,
and this patch does that.

Build up textChunk.str more efficiently.
...
PartialEvaluator.getTextContent() builds up textChunk strings 1 char at a time,
creating many 100s of 1000s of intermediate strings along the way. This patch
make it instead push chars to an array and then join them at the end, as we
have done in numerous other places.

This new function is much faster than ensureRange(pos, pos+1), which is a very

This speeds up the rendering of some test cases (including the Tracemonkey
paper) by 4--5%.
