usage: This tool analyzes the commit range between <of> and <until>. It finds commits which belong together e.g. Implement/Revert pairs and Implement/Port/Revert triples. All supplied hashes need to be from the same branch e.g. master.

This introduces a simplified allocation operator which can be used to
model inline allocations in TurboFan. It is currently used for context
allocations, but still disabled because change lowering introduces
floating allocations outside the effect chain that interfere.

port 83a0af5500 (r28165).
original commit message:
VectorICs: built-in function apply should use an IC.
Handled a TODO that sent builtin function apply to the runtime on property get.

Reason for revert:
[Sheriff] Speculative revert. This seems to block the current roll:

- all RegisterAllocatorTest unit tests passing, when unittest has the flags: --turbo-filter=* --always-opt --turbo-deoptimization --turbo-verify-allocation --turbo_greedy_regalloc
./tools/run-tests.py passing when providing --turbo_greedy_regalloc, but still having some failing (more than the "normal" 43) when passing all the flags. I realize just passing --turbo_greedy_regalloc does not provide full coverage, but it did uncover some bugs, still
The CL centralizes the computing of split points (for "losing" intervals) with the determination of whether an interval is irreducible, and, therefore, of infinite spill weight (if an interval can't be split or spilled, it can't lose in weight comparison because there's nothing we can do to it and make progress).
There are allocator efficiency opportunities I haven't yet taken (this refers to the code itself, not the generated code). For example, the above split/spill computation can be cached. My plan is to defer this to at least after we see numbers showing the value of the algorithm, and potentially do at the same time we remove the linear algorithm, if that is still the plan. At that time, we can look where some APIs best belong (e.g. weight computation may fully live and cache itself on LiveRange)
In addition, the CL adds a few debug-time-only Print APIs I found very useful: on demand (while in GDB) dump of the code, live range info (use positions & operand description, and intervals), etc.

Just give internal ones an ArrayBuffer with a NULL backing store. This
simplifies the access checks a lot.

Implements the strong mode proposal's restrictions on implicit conversions
for the binary + operator. Test suite is also cleaned up/refactored to allow
easier testing of the comparison operators in the future.
