TurboFan expects the offset input of a Load or Store node to be a
pointer-size input, i.e. an int32 input on 32-bit platforms, and int64
on 64-bit platforms. In WebAssembly we always provided 32-bit offset
though, which caused problems when the high word of the register which
contained the offset was not empty.
With this CL we change the offset input to int64 on 64-bit platforms.
In addition we also change the type of the memory_size_ node to int64,
so that that we do not have to adjust the type of the memory size at
every memory load.
This CL will cause performance regressions but is necessary for
correctness and to avoid crashes.

A while ago, CharacterRange::AddCaseEquivalents used to operate on a
single range (the `this` value) and add case equivalents for that to
`ranges`.
This was changed in a2baaaac to use `ranges` as a list of incoming
operands instead. When we now determine that the current range does not
have case equivalents, we need to `continue` instead of `return` to
avoid skipping the remaining ranges in the list.

The DoubleToI stub is no longer called outside of TurboFan, and always in the
same way:
- The parameter is on top of the stack.
- The stub is always called in a slow path.
- It truncates.
Therefore, we can simplify it to only support this case and remove dead
code.
On top of this, since the stub is always considered to be on a slow path for all
backends, this patch takes the opportunity to remove the `skip_fastpath`
optimisation. This would generate a stub which does not handle all inputs,
assuming that the backend already handled some of the inputs in a fast
path. Removing this allows the stub to have the same behaviour on all targets.
On Arm, this patch reworks the stub a little. We could use ip instead of saving
and restoring a register on the stack. Also, comments would mention that we
assume the exponent to be greater than 31 when the it can be 30 or higher. As
done for Arm64, let's check this at runtime in debug mode.
On Arm64, we can also implement the stub without pushing and poping off the
stack. It needs 2 general purpose and a double scratch registers which we have
reserved already (ip0, ip1 and d30). This removes the need to check that the
stack pointer is always 16-bytes aligned.
Finally, this also fixes a potential bug on Arm64, in the
`GetAllocatableRegisterThatIsNotOneOf` method which is now removed. We were
picking an allocatable double register when we meant to pick a general one.

Removes the interrupt check and runtime call to TryInstallOptimizedCode
from the optimization marker checks (i.e. CompileLazy and
InterpreterEntryTrampoline). Instead, we rely on the other interrupt
sources (in particular stack checks at function entries and loop
headers) to install optimized code for us.
This will hopefully not cause regressions, as we have plenty of other
interrupt checks, but it may delay optimized code execution for
some function by one function call.
