If there is still Liftoff code installed on a function, we cannot reuse
it when tiering down, since we don't know if it was compiled with
debugging capabilities. This made the "debug-step-into-wasm" test flake.

Instead of two copies of the lookup code in frames.cc and wasm-debug.cc,
put one lookup method on the WasmCode. This is where it belongs really,
since the WasmCode is the main input to the function (besides the
offset).

Also refactor how source positions are computed in WasmCompiledFrame.
Avoid going through the summary, which is unneccessarily complex. This
also adds another {byte_offset} accessor which can be used for
debugging.

especially why {ldrexd} is used. This CL adds some documentation to
make it more understandable.

Additionally this CL changes the code generation to use {cmp} instead
of {teq}. It's the preferred (idiomatic) sequence on Arm.

Adding code can happen in parallel (it includes copying the code to the
code region and relocation it). Publishing happens under one lock per
native module though. We eventually want to avoid blocking on this lock
for too long. This CL prepares that by splitting the actions of adding
and publishing code.

This reverts commit 10360127.

Reason for revert: This fix only had moderate impact and the
underlying CPU bug has now been addressed.

Original change's description:
> Speculative fix to crashes from a CPU bug
> 
> For the last few months Chrome has been seeing many "impossible" crashes
> on Intel Gemini Lake, family 6 model 122 stepping 1 CPUs. These crashes
> only happen with 64-bit Chrome and only happen in the prologue of two
> functions. The crashes come and go across different Chrome versions.
> Analysis of most of the crashes shows that the address of the crashing
> instruction follows some patterns:
> 
> When crashing in GetFieldIndex() the last byte of the address is always
> 1c, 5c, 9c, or dc.
> 
> When crashing in UpdateCaches (fewer unique samples) the last byte of
> the address is always 5d or 9d.
> 
> The address of the function is 0xc or 0xd bytes earlier so the crashing
> functions always start with an address that ends in 10, 50, 90, or d0.
> 
> Those addresses are for the crashes on a load of the __security_cookie.
> The crashes also occasionally happen on the two instructions that follow
> the __security_cookie load in which case the crashing instruction's
> address has been seen to end with 23 or a3. This corresponds to a
> function start address of 10 or 90.
> 
> Since the crash involves reading incorrect instruction bytes when
> crossing a 16-byte boundary and since the crash appears to only happen
> with particular 16-byte alignments it seems reasonable to force the
> function's alignments to a multiple of 32 to see if this reliably
> avoids the crashes. This change uses the gcc/clang __attribute__
> directive to force 32-byte alignment. I have tested this change enough to
> verify that it triggers the desired alignment (with up to 31 "int 3"
> instructions added for padding) but since I have never reproduced this
> crash I have no way of testing its efficacy.

We cannot rely on the clang compiler to generate the trampoline entry
and the right mangling because `__attribute__((naked))` does not
prevent clang from generating TSAN function entry stub
(`__tsan_func_entry`). Even with `__attribute__((no_sanitize_thread)`
annotation clang generates the entry stub.

The difference to Chromium is that we support frame pointers and thus
integrate better with debugging in e.g. gdb.

From recent discussions on https://crrev.com/c/2057355 it became clear
that the FixedRawData serializer bytecodes need to be refactored. This
CL

- updates documentation to correctly specify that data length is given
in kTaggedSize unit, and
- changes the way smi roots are serialized s.t. deserialization no
longer needs hacks to be correct on big-endian architectures and when
(theoretically) deserializing sequences of smi roots. We do this by
serializing the full object slot for smi roots instead of just the
smi contents.

For keyed stores we recompute handlers based on the receiver maps
we have seen. This is done so that we can transition to the most generic
elements kind we have seen so far. When we recompute this handlers we
get a new prototype validity cell and ignore the existing cell. This
leads to incorrect behaviour if the cell was invalid. Recomputing the
handler may be extra work which is not worth doing at this point. So
we just reuse the existing validity cell and let the IC recompute the
handler if we see the map again.

This reverts commit 8f68e392.

Reason for revert: depot_tools started using Python3 by default with this deps roll, but it contained a Python3 bug. Reverting this and waiting for a new deps roll will fix the issue since the latest depot_tools contains the fix for this issue.

Original Commit Message:

  This is the same cleanup as in the previous CL, but for {EmitBinOpImm}.
  This requires a minor change in the name of the emit functions with
  immediate, to make them distinguishable from the emit functions with two
  registers. We just append an "i" to the functions with immediate.

Use inline asm to generate the x64 PushAllRegistersAndIterateStack
which is the trampoline for conservative stack scanning. Keep the
function definition as C code to allow clang to generate the correct
mangling for each platform.

This approach has the benefit that it immediately works for all
platforms that support clang.

The trampoline should never inline the actual iteration method and
always use a full call. As a result, there can be no interesting data
in the redzone.

This allows simplifying as the existence and size of a red zone is platform
dependent.
