934565 - Don't clear op queue all the time

Status: NEW

(Core :: DOM: HTML Parser, defect, P5)

Description

[Olli Pettay [:smaug][[e-mail]]]

Attachment: WIP

Currently we pretty effectively clear mOpQueues once we have finished parsing.
Then when we next time parse again we need to do bunch of allocations.

The patch caches too much and I didn't even look at in which cases Clear() would be fine. Just replaced all the explicit .Clear() calls with ClearOps().

The test results for bug 922018 varies a lot, but ~5% speed up here.

Bulk-downgrade of unassigned, >=3 years untouched DOM/Storage bug's priority.
