This CL fixes two unrelated issues in Turbofan that contributed to
non-determinism:
- Most importantly, external references included their address in the
  node hash, but they're unpredictable due to ASLR. Fix by only looking
  at the lowest bits assuming a 4K page size.
- BranchElimination didn't properly trigger revisits for the
  IfTrue/IfFalse projections.

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.

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.

> In addition this CL removes the test mjsunit/regress/wasm/regress-789952.
> This test defined an invalid WebAssembly module and expected it to

> The module is invalid because it defines the length of the custom section

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.
