The motivation is being able to build Chrome/Mac/Intel on an Apple Silicon mac. Depends on https://chromium-review.googlesource.com/c/chromium/src/+/3348020 - Correctly set v8_snapshot_toolchain when targeting x64 on an arm64 host (always use the clang_ toolchain for now since that's all that's needed at the moment) - Check V8_HOST_ARCH in immediate-crash.h. In V8 terminology, "host" is the machine the snapshot generation runs on, while "target" is the machine that V8 runs on when it JITs. IMMEDIATE_CRASH runs on the host. Up to now, target arch x64 implied host arch x64 so the old code happened to work too, but this is the correct macro (and it makes this cross scenario work). - In assembler-x64.cc, only compile the code that probes the current CPU when running on an intel host. (There's an early return for snapshot generation anyways.)
