Refactored text blob backend for improved performance: instead of using separate buffers for runs/positions/glyphs, everything is now packed in a consolidated slab (including the SkTextBlob object itself!). Benefits: * number of allocations per blob construction reduced from ~4 to 1 (also minimizes internal fragmentation) * run record size reduced by 8 bytes This takes the blob construction overhead down to negligible levels (for the current Blink uncached textblob implementation). Unfortunately, the code is much more finicky (run merging in particular) -- hence the assert spree. Multi-run blobs are vulnerable to realloc storms but this is not a problem at the moment because Blink is using one-run blobs 99% of the time. Will be addressed in the future.
