In case there's no exact match for the breakable location in SetBreakpoint(), don't try to find the syntactically closest break location, but rather find the first possible break location in bytecode order. In particular when trying to set a breakpoint in a line with for-of or an array destruction, there's no point in going for the syntactically closest to the beginning of the line, but rather go for the semantically first, as the intiution for setting a breakpoint on a line is that the debugger stops before it executes anything on said line. In the example ``` var [^a, ^b] = ^func(); ``` there are three possible break locations, and the correct one is the last one as the call to func will happen first at runtime. For generators that's currently broken because of the implicit initial yield, and same with modules (see crbug.com/901819), so we keep the previous behavior of finding the closest breakable location, and will fix that independently in a follow up CL.

Pinned registers were not considered correctly when taking a volatile register. This CL refactors handling of the pinned registers list by combining the candidates list and the pinned list early. This avoid additional parameters on some functions and might save some redundant masking. As a side effect, it also fixes the DCHECK error on arm.

We made two runtime calls: The first one allocated the exception object containing a FixedArray of exception values, the second call did the actual throw. Inbetween the code was filling the values array. This CL refactors this to only allocate the FixedArray initially, fill it, and then allocate the actual exception and throw it both from the second runtime function. This avoids a WasmGetOwnProperty call to find the values array.

The csuite.py script does not work correctly on Windows. It runs correctly in baseline mode, but there are two problems when running in compare mode: 1. In compare mode the output of benchmark.py is piped to the compare-baseline.py script, but Windows only execute python files if python.exe is the default program to open '.py' files, and this is not the case, by default, when python is installed as part of the depot_tools. Fix: explicitly add the 'python' command before compare-baseline.py. 2. By default CSuite prints the results to stdout using escapes codes that add color highlights. But this does not work on Windows when compare-baseline.py is launched with a pipe: python test/benchmarks/csuite/benchmark.py <...> | python test/benchmarks/csuite/compare-baseline.py <baseline_results> Fix: Do not use a pipe. Write the benchmark numbers for the compare-run into a separate file, and pass the path to this file to compare-baseline.py Change-Id: Ic22d5bd4b47901f0ba0f35bc2496441346d21c6a Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2656855Reviewed-by:Michael Stanton <mvstanton@chromium.org> Commit-Queue: Paolo Severini <paolosev@microsoft.com> Cr-Commit-Position: refs/heads/master@{#72807}

Port adf035fb Original Commit Message: This CL avoids redundant loads of the instance from the frame by caching it in a register if possible. This register will be the first one to be cleared once we run out of registers (hence it's called a "volatile register"). On local tests, this seems to reduce most redundant loads within a function, and it also reduces the load for the stack check in the function prologue. After the stack check, we need to discard the cached instance though, since the potential runtime call for the stack check might clobber it. This will be addressed in a follow-up CL by re-loading the cached instance after the stack check. This is expected to remove another good chunk of instance loads, because the instance would initially be available in a register when starting the function code.
