Turning on V8_ENABLE_SYSTEM_INSTRUMENTATION by default has broken node-v8 builds on Windows, tracked here: https://github.com/nodejs/node-v8/issues/192. It looks like it is due to the fact that Node uses pre-compiled headers, which undefines some macros needed for the event trace APIs to work. (see src/base/win32-headers.h) Bug: v8:11043 Change-Id: I3a6caeaaabab59d42e14b79defb2e37efd9ad04d Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2830550Reviewed-by:

The compiler/fast-api-interface-types test is incompatible with jitless and stress_snapshot, so this CL disables it on these two variants.

This saves quite some code space on wasm functions, which often do not spill any tagged values (hence the safepoints will just be empty). It also often saves a few bytes on code that actually spills tagged values, but not to the highest frame slots.

Port ede5e814 Original Commit Message: This reverts commit d16eefe0. It is not correct to check for node equality during the graph construction phase, because we can have optimizations that will combine same nodes. So it can happen that in wasm-compiler, the inputs to shuffle are not the same, so we canonicalize using that knowledge that it will not be the same, and allow indices > 15. But later we can have optimizations that combine the 2 inputs (e.g. splat of the same constants), and the instruction selector will see that the input nodes are the same.
