This CL adds support for inlined functions in Turbolizer. It is also a
refactoring of the Turbolizer code-base. Most importantly, handling of
source positions changed to exact source positions, and not code ranges.
This improves selection interoperability between different phase views.
A separate CL changes the Turbolizer JSON format to include inlining
information. This Turbolizer update, however, is intended to be backwards
compatible with the JSON format Turbolizer generated before the JSON
format change.

This is needed since depot_tools may not be in PATH on LUCI bots. Using the copy
of depot_tools that contains the recipes is also incorrect as it is not
guaranteed to contain binaries that do not have corresponding recipe API, which
does not apply to script called from a recipe. This also protects our release
scripts from breaking due to arbitrary changes to depot_tools.
Chromium also pins depot_tools for similar reasons:

There are likely cleanups that can be done after this CL:
- context-related functions in the interpreter and compiler take ScopeInfo as
well as ScopeType and slot-count as input. The latter 2 should be directly
derived from the former. We should be able to drop FunctionContextParameters.
- ContextExtension is probably not needed anymore, since we now always have the
correct scope_info directly in the SCOPE_INFO_INDEX slot.

During code generation, we generate self-references (i.e. references to
the Code object currently being generated) as references to a temporary
handle. When the final Code object has been allocated, the handle's
location is fixed up and RelocInfo iteration fixes up all references
embedded in the generated code.
This adds support for this mechanism to the builtins constants table
builder. CodeObject() is now a new handle pointing to a dedicated
self-reference marker in order to distinguish between self-references
and references to undefined. In Factory::NewCode, we patch up

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.
