4428cebdbc Add ChunkedStream.ensureByte().
This new function is much faster than ensureRange(pos, pos+1), which is a very
common case.

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

22a0e7fe65 Optimization for FlateStream_getCode, making more pdfs parsable.
This commit cleans up the FlateStream_getCode method, and removes a few error
conditions.
Previously it would fail if the codeSize is less than maxLen if end of stream
is reached. However in the document linked below there is a sub-stream
(the one starting at pos 337) which has maxLen set to 11, but actually
contains only 10. After breaking the sanity check still applies, and in this
case passes validating codeSize(10)==codeLen(10).

0a42edf82f Optimize JPG.js receiveAndExtend for 1 bit case.
Profiling showed that receiveAndExtend is frequently called with the length of
one bit. This happens for example in decodeBaseline.
For a single bit, the loop and shift in receive, as well as the shifts in
receiveAndExtend are overhead.
This shortcut manually calculates the shifts by either returning 1 or -1 from
receiveAndExtend by reading the bit and deciding on the return value.
While it comes with an overhead for each non-one length, the speedup is at about
10% in the hot parse/decode path.

dcde59fa76 Optimized loops in JPG conversion.
This change makes the 4 conversion loops look the same.
It optimizes access of the array length and access of the property
numComponents, which is known to be constant.
