This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:
When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.
The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.
Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

When attributing ticks to a function, we first check if the current pc
matches a section within the dynamic library. If we find a match here,
then we don't continue looking within dynamically generated range
information, e.g. for JS functions and builtins.
This logic breaks when embedded builtins come into play. They live
within the libv8.so shared library, and are found when looking up
statics. But what we really want is to look up the dynamically
generated code-range, which contains more precise information.
In this CL, this case is detected by matching the found symbol name.
If it's the embedded blob, then we continue to dynamic lookup.

This makes testing with random gc stress use the status file entrees
for gc fuzzing as well, since many test cases not suitable for one, are
not suitable for the other.
This also skips two more tests that rely on assert(Un)Optimized, which
is unreliable with gc fuzzing.

can be found here: https://bit.ly/2qAI5Ep
Note that there is quite a bit of work left to do in order to get
Torque production-ready for any non-trivial amount of code, but
landing the prototype as-is will allow for much faster iteration.
Bugs will be filed for all of the big-ticket items that are not
landing blockers but called out in this patch as important to fix.

Before Turbofan/Ignition it was possible to use external profilers to
sample running V8/Node.js processes and generate reports/FlameGraphs
from that. It's still possible to do so, but non-optimized JavaScript
functions appear in the stack as InterpreterEntryTrampoline. This commit
adds a runtime flag which makes interpreted frames visible on the
process' native stack as distinguishable functions, making the sampled
data gathered by external profilers such as Linux perf and DTrace more
useful.
