Don't release HTMLToken::m_data's storage between tokens

This was causing us to thrash malloc when parsing documents
which had text-nodes larger than 256 characters.

This drops another 4% off of the benchmark.

MSE: Update tests to expect failure w.r.t. Chromium LegacyFrameProcessor duration logic change

Chromium-side change to LegacyFrameProcessor to use frame duration, if
available, during AppendWindow filtering and IncreaseDurationCB will
cause layout tests to fail until they are updated.

This change adds those failure expectations plus WebM (and relevant unprefixed MSE MP4) expectation
updates that work locally after the Chromium-side change
(http://codereview.chromium.org/205703003) is applied (and for MP4 layout testing, with webm codec
support locally disabled in Chromium stream parser factory).

TEST=All media layout tests pass locally on Linux before and after the Chromium-side change is applied (including relevant MSE MP4 tests)

Check transform() before dereferencing it.

hasTransform() does not mean transform() is non-null.
