Can we use WTF's Seconds class instead of double for all this timeOrigin passing?

restrictedMarkFunction in PerformanceUserTiming.cpp is not thread safe.
Please fix that before landing this patch.

I don't think we can get rid of Intel's copyright.

That is because my git diff thinks we are copying this file from PerformanceMeasure.idl, but we aren't. This is a new file with WebIDL just copied from the spec (extracted from Performance.idl).

[PATCH] Additional Changes

These additional changes (mostly tests and a minor tweak to User Timing for Workers) came up because of some comments rniwa raised in person.

I haven't forgotten about moving to MonotonicTime / Seconds classes. I have that patch right now but I'll put it up for review as a follow-up since it reaches into more and more places not relevant for this bug. Also, converting everything related to Performance APIs at once will be nice.
