Move load splat and load extend ops into the list of SIMD memory opcodes, since they similarly take an i32 and an memarg. This fixes the OpcodeLength calculation in function-body-decoder-impl.h. And in turn, fixes the mjsunit test code that the fuzzer generates. See the regress-1055692.js file for the weird S8x16LoadSplat followed by 2 kExprUnreachable, where the kExprUnreachable really is a memarg {0x0, 0x0}. This bug was caught by the fuzzer, and that was the generated test (with small fixes to add kExprDrop), so leaving it as it is.

This extends the existing test to also print scope information on every break. Note that the currently printed information is not correct, since register values are not reconstructed yet. We just always print {-11} for register values. Thus the expected output will change with follow-up CL.

Context: This is part of a bigger CL: https://chromium-review.googlesource.com/c/v8/v8/+/2043840 In order to get rid of the arguments adaptor frame, we will reverse the JS arguments in the stack. Some macros will need to reverse its arguments as well, we will do that using helper macros in another CL (see src/builtins/builtins-descriptors.h in 2043840). For that we need to stringify the name kDontAdaptArgumentsSentinel, which cannot be done if '::' is in its name. This CL should not have any impact performace/memory on V8.

We use the same interrupt to both allocate feedback vectors and for updating the profiler ticks. If there is a feedback vector already available, we just increment the profiler ticks that we use to mark for optimizing function. Calling JSFunction::EnsureFeedbackVector allocates a feedback vector, but doesn't reset the budget, so we optimize much earlier than expected. This is currently only a problem with %PrepareFunctionForOptimize that doesn't reset the budget. Other code paths do also reset the interrupt budget.

This extends the debug side table to also store register locations in addition to constants and stack values. Previously, every value that was not constant was assumed to be spilled to the stack. This made sense, because without breakpoints we would only emit debug side table entries at call sites, where all registers are spilled. With breakpoints, this changes. At break locations, values might be live in registers. The logic to decide whether a value will live in the register or on the stack is extended, because we sometimes generate the debug side table entry at a point where the registers are not spilled yet. The debug side table entry creation needs to account for that, and assume that these registers will still be spilled.

The Python builtin `basestring` has been removed from all [currently supported version of Python](https://devguide.python.org/#status-of-python-branches) so define `basestring` in Python3 so that line 60 does not raise a NameError at runtime.

Given two registers that are both not gp_pair, one could be an fp_pair, and the other not, and we will incorrect call == on them. The current check needs to be expanded to check that both registers are fp_pair.

This extends the existing wasm profiling test to also check that wasm-to-js and js-to-wasm wrappers appear in the profiles as expected. It thus serves as a regression test for the status quo.

Make sure the "initial pages" memory limit is enforced correctly and throws a CompileError when exceeded. Bump the "maximum pages" memory limit to 65536. The --wasm-max-mem-pages flag now controls the "initial pages" limit; the "maximum pages" limit is always 65536 as spec'ed. This CL depends on https://github.com/WebAssembly/spec/pull/1121.
