This also avoids flushing when bounds checking the identity popup for visibility.

Adds another restyle generation which represents the dirty state of raw
style changes, so that getComputedStyle() wont be confused by optimizations
made by style engines.

Previously, we submitted polygons as a list of triangles, duplicating
some ancillary data with each vertex. As we move away from constant
buffers for some of this ancillary data, it will bloat the size of each
vertex. To avoid this, we will now instance over a unit triangle
instead. Each instance contains three triangle coordinates and ancillary
data can be shared between them. The target vertex is computed similarly
to how we handle rects in the unit quad shaders.
Since bug 1378258 remove malloc_print_stats, there are a bunch of
allocator stats that are now unused, reducing the memory footprint of
allocator metadata.

When initializing a new chunk for use as an arena, we started by zeroing
out the chunk (if that wasn't the case) and then initializing a new
arena chunk in there. It turns out this can have a noticeable overhead,
especially when e.g. the new arena chunk is used for a large allocation
filled out by something that is realloc()ated.
OTOH, the chunk recycle code only ever keeps zeroed or arena chunks
around (there is a "recycled" type too, but in practice, at the moment,
this means they were arena chunks before). Arena chunks that were
recycled were totally emptied, so all the runs they may contain will
contain zeroed-out or poisoned data. They also contain a header, that is
overwritten by the new arena chunk initialization.
This means we can get away with reusing non-zeroed recycled chunks
without zeroing them, as long as the arena chunk header marks the runs
as madvised instead of zeroed.
Code-wise, this would benefit from getting a ChunkType out of
chunk_alloc, but this would require more refactoring than I'm willing to
do at the moment.
