The unittests test if the trap handler only handles those traps it is supposed to handle: * Only handle traps when the thread-in-wasm flag is set. * Only handle traps of the right type, i.e. memory access violations. * Only handle traps at recorded instructions. The tests also test the consistency of the thread-in-wasm flag. I made one change in the trap handler where that consistency could be violated. All tests are executed with the default trap handler provided by V8, and with the trap handler callback installed in a test signal/exception handler.

This patch gives DescriptorArray its own visitor id and its own layout that is independent from the layout of WeakFixedArray. This allows us to use raw 16-bit integers for keeping track of the number of descriptors (total, non-slack, and marked). As a side-effect, we save one word per descriptor array on 64-bit. v8:8486 Change-Id: If8389dde446319e5b3491abc948b52539dba235c Reviewed-on: https://chromium-review.googlesource.com/c/1349245 Commit-Queue: Ulan Degenbaev <ulan@chromium.org> Reviewed-by:

Instead of calling a special import wrapper that converts arguments to tagged values by boxing, we can now generate calls to little WASM stubs that contain a single WASM bytecode each.
