This tool can quickly check all nanobench tests including svgs
and skps (<5 minutes for CPU, ~30 minutes for GPU) and find
significant performance regressions without much noise.
This tool is not only faster (lower latency to get regression
alerts), but also more sensitive compared to our k-means and
step-fitting bots (especially for changes that only affect very
few benches). It may still miss some regressions, but the
regressions reported should be valid with very high probability.

After the change is uploaded to Android, developers can trigger TH and download binaries (if required) after runs complete.
The script re-uses the workdir when it is run again. To start from a clean slate delete the workdir.

The ubidi code only works with utf16 and SkTextBlob only with utf8. This
requires translating indexes. The current code starts cold when
translating indexes for each run, leading to taking O(n^2) time on the
number of runs. However, since this code is iterating over the runs in
order and each run begins where the last left off, simply keeping the
previous run's utf8 and utf16 end positions and using them as the next
starting position makes this O(N).

We like a LIFO default thread pool in tools like DM for better
memory/time locality... the bots use less memory this way, and
generally run faster.
But most use cases want a FIFO queue, so that they can get going
on the next parts of early work while later work is still running.
This splits the implementation into one using SkTArray and pop_back
for LIFO, and a new one using std::deque and pop_front for FIFO.

On Macs the user process limit is low, in the hundreds, and it's a
little annoying to mysteriously find other programs fail to start
because ok is greedily slurping up all the available process capacity.
On Linux the user process limit is up in the ten-thousands, so I don't
expect this to matter there, even on Android. I haven't seen any
significant speed difference imposing a default ncpus limit.

Chrome would like to perform cpu-side preprocessing for gpu draws in parallel.
They do not want to go through a picture (since they have their own display list format).
The general idea is that we add a new SkDeferredDisplayListRecorder class to
perform all of Ganesh's cpu-side preprocessing ahead of time and in parallel.
The SkDDLRecorder operates like SkPictureRecorder. The user can get an SkCanvas
from the SkDDLRecorder and feed it draw operations. Once finished, the user
calls 'detach' to get an SkDeferredDisplayList. All the work up to and
including the 'detach' call can be done in parallel and will not touch
the GPU. To actually get pixels the client must call SkSurface::draw(SkDDL)
on an SkSurface that is "compatible" with the surface characterization
initially given to the SkDDLMaker.
The surface characterization contains the minimum amount of information Ganesh needs
to know about the ultimate destination in order to perform its cpu-side work
(i.e., caps, width, height, config).

This adds a fallback backtracer for use on Android where <execinfo.h>
ins't present, instead using <unwind.h> to unwind and <dlfcn.h> to
lookup function names and addresses.
lockf() wasn't available until NDK API 24, so I've just no-op'd file
locking on older targets. I tried switching from lockf() to flock(),
but flock() didn't see to _do_ anything, neither on Android nor on my
Mac laptop. I think I should be able to use the lower-level fcntl()
APIs to restore file locking uniformly in a follow-up. The upshot is
until then, we'll have interlaced logs and stack traces on Android
devices unless you set ndk_api=24 in GN.
We need to add a couple build flags to make backtraces useful:
* -funwind-tables makes the call to _Unwind_Backtrace() actually
traverse the call stack. This is a small extra binary size cost.
* -rdynamic makes symbols linked into the main executable visible
to dladdr(). We do this on Linux already for the same reason.

All information needed by the thread is captured by the prepare
callback object, the lambda captures a pointer to that, and does the
mask render. Once it's done, it signals the semaphore (also owned by the
callback). The callback defers the semaphore wait even longer (into the
ASAP upload), so the odds of waiting for the thread are REALLY low.
Also did a bunch of cleanup along the way, and put in some trace markers
so we can monitor how well this is working.
