Poisoning unmarked objects serves two purposes: - Prohibits finalizer from accessing other unmarked objects; - Unpoisioning also clears potential poisoning of the embedder which is necessary as the sweeper and compactor modify the payload of objects; Bug: chromium:1056170 Change-Id: I4346a0ab736603b3d6170b41b0e7255db1452897 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2762137Reviewed-by:

One of the x86 ISA extensions is confusingly named SSSE3 (*Supplemental* Streaming SIMD Extensions 3). SSSE3 supersedes SSE3, and is superseded by SSE4. This CL adds testing coverage for x86 CPUs that support SSE3 instructions, but do not support SSSE3 instructions. Chrome supports these CPUs, and they are used by a non-trivial amount of Chrome's users on Windows.

Torque generally supports marking things as unused by adding a single underscore to the front of identifiers. For locals, this feature works fine. For macros, it's only half-implemented: attempting to look up a macro that starts with _ fails (as it should), but the compiler also complains if the macro is unused. This change avoids emitting the latter error.

This changes the behavior of SetBreakpointForScript to find more accurate break positions. Previously, setting a breakpoint would only consider the shared function info that contained the requested position for setting a breakpoint. More intuitively, a breakpoint should not necessarily be set in a function that contains the position, but in the closest breakable location that comes after the position we requested. To achieve this we: 1. find the shared function info of the inner most function that contains the requested_position. This function's end position is used to find other shared function infos in step 2. 2. search for all shared function infos that intersect with the range [requested_position, inner_most_function.break_position[. 3. From the shared function infos extracted in 2, find the one that has the closest breakable location to requested_position.
