For each intrinsic/runtime function we define in runtime.h, an inline
version is automatically declared. We only ever use 24 of the inline
functions. Even though we don't call the other ones, macro magic means
they still take up space by existing in various arrays and tables like
kIntrinsicFunctions. They also create code in switch statements.
Some drive-by cleanups:
- Remove the switch in NameForRuntimeId() and just use the table of
runtime functions to lookup the name directly.
- Remove tests for IsFunction, ClassOf and StringAdd intrinsics as
they are the last users of the inline versions of these.
- Remove the MaxSmi inline version as it is only used in tests.
Saves 64 KiB binary size.

When converting a Signed32\/MinusZero value from Word32 to Float64
representation or just passing it through as Word32 (with potential
type checks on it) we don't need to worry about -0 as long as the uses
identify 0 and -0.
Drive-by-fix: Fix the CheckChange() helper in the representation
changer test to pass Truncation::Any() by default.

Teach TurboFan about representation changes from Float64 to Word64 where
the input value is already known to be within the Int64 or Uint64 range.
While not all of these values have representations in Float64, those
that do can be converted to Word64 without loss of precision.
Same is true for Tagged to Word64 conversions, although here we don't
(currently) need the case for Uint64 ranges, so we can skip adding an
operator for that until it becomes necessary (there's a hard check in
the code so it'll not silently cause trouble).

This change introduces the necessary conversion operators to convert
from Word64 to other representations (Tagged, Word32, Float64, etc.),
and plugs in the Word64 representation for NumberAdd/NumberSubtract,
such that TurboFan will go to Int64Add/Sub on 64-bit architectures
when the inputs and the output of the operation is in safe integer
range. This includes the necessary changes to the Deoptimizer to be
able to rematerialize Int64 values as Smi/HeapNumber when going back
to Ignition later.
This change might affect performance, although measurements indicate
that there should be no noticable performance impact.
The goal is to have TurboFan support Word64 representation to a degree
that changing the TypedArray length to an uint64_t (for 64-bit archs)
becomes viable and doesn't have any negative performance implications.
Independent of that we might get performance improvements in other areas
such as for crypto code later.

This adds support to TurboFan's representation selection for the Word64
representation, and makes use of that to handle indices for memory access
and allocation instructions (i.e. LoadElement, StoreElement, Allocate,
etc.). These instructions had previously used Word32 as representation
for the indices / sizes, and then internally converted it to the correct
representation (aka Word64 on 64-bit architectures) later on, but that
was kind of brittle, and sometimes led to weird generated code.
The change thus only adds support to convert integer values in the safe
integer range from all kinds of representations to Word64 (on 64-bit
architectures). We don't yet handle the opposite direction and none of
the representation selection heuristics for the numeric operations were
changed so far. This will be done in follow-up CLs.
This CL itself is supposed to be neutral wrt. functionality, and only
serves as a starting point, and a cleanup for the (weird) implicit
Word64 index/size handling.

With ReadOnlyRoots and GetIsolate on JSReceiver, we can remove almost
every isolate parameter from <Object>::Print. The remaining ones, like
Map, are special-caseable for read-only maps, and as a result we can
remove isolate parameters from <Object>::Print entirely.
This patch also opportunistically cleans up a few places where isolates
were only needed for Object::Print, such as TransitionAccessors and
DescriptorArrays.

- Move the CompilationDependencies member of OptimizedCompilationInfo
to Turbofan's PipelineData (and thus into the compiler namespace).

This CL surfaces AssemblerOptions to CodeAssembler::GenerateCode and
to pipeline methods. To allow forward declaring AssemblerOptions,
AssemblerBase::Options was moved out of the AssemblerBase class.

This is a reland of 4b9b9b6845, which
accidentally disabled optimization after dependency changes (instead
of retrying).
