This change adds the indexed field for the characters in the definition
of sequential string types, and introduces support for recognizing the
various specific string types in v8_debug_helper. In an attempt to
avoid duplicating info about string instance types, it also refactors
String::Get so that StringShape (a simple class usable by postmortem
tools) can dispatch using a class that defines behaviors for each
concrete type.

This new FreeList should be a reasonable replacement for our old
FreeListLegacy: it is slightly less efficient (~1%), but uses much
less memory (often 5% less old_space size).
It is based on FreeListMany, with the following additions:
- A cache to waste less time iterating empty categories
- A fast path for allocations done in the runtime and generated code
- A slow path (the same as FreeListMany actually) for allocations
done in the GC.

For import wrappers, we add a special "callable" parameter as the last
parameter. This parameter is not set in the TurboFan graph but in the
code generator. Therefore this parameter has to be allocated in a
special register and cannot be lowered generically. With this CL we
detect in the CallDescriptor lowering if the last parameter is this
special "callable" parameter. If so, we preserve it in the lowered
CallDescriptor in the same register.

This CL adds a mechanism that prevents the RuntimeProfiler from
triggering optimization of a function after
%PrepareFunctionForOptimization has been called. This is useful to
prevent flakiness in tests, as sometimes a function that already
got deoptimized would receive a new code object from a concurrent
compile that was triggered by a heuristic just in the right moment
for the assertUnoptimized test to fail. For example, the following
was happening:
PrepareFunctionForOptimization
[marking `testAdd` for optimized recompilation, reason: small function]
[concurrently compiling method `testAdd` using TurboFan]
[manually marking `testAdd` for non-concurrent optimization]
[synchonously compiling method `testAdd` using TurboFan]
[synchonously optimizing `testAdd` produced code object 0xAAAA - took 1.638 ms]
Runtime_GetOptimizationStatus OPTIMIZED `testAdd` (code object 0xAAAA)
DeoptimizeFunction `testAdd` with Code Object 0xAAAA
[concurrently optimizing `testAdd` produced code object 0xBBBB - took 3.377 ms]
Runtime_GetOptimizationStatus OPTIMIZED `testAdd` (code object 0xBBBB)

Forge (Google3) can only run 64-bit executables. As Torque runs as part
of the build process, we need a 32-bit "cross-compile" mode when
we target 32-bit architectures. Note that this flag won't be needed
in Chromium/V8 land, since we build V8 with the same bit width as
the target architecture.
This CL adds a new runtime flag to torque "-m32". When enabled, the
flag forces 32-bit word sizes for various pointer/word sizes. By
default, the host system sizes from {src/commons/globals.h}
are used.

This is another step towards considering the unoptimized frame size in
stack checks within optimized code.
With the changes in this CL, we now keep track of the maximal
unoptimized frame size of the function that is currently being
compiled. An optimized function may inline multiple unoptimized
functions, so a single optimized frame can deopt to multiple
frames. The real frame size thus differs in different parts of the
optimized function.
We only care about the maximal frame size, which we calculate
conservatively as an over-approximation, and track in
InstructionSelector::max_unoptimized_frame_height_ for now. In future
work, this value will be passed on to codegen, where it will be
applied as an offset to the stack pointer during the stack check.
(The motivation behind this is to avoid stack overflows through deopts,
caused by size differences between optimized and unoptimized frames.)
Note that this offset only ensure that the topmost optimized frame can
deopt without overflowing the stack limit. That's fine, because we only
deopt optimized frames one at a time. Other (non-topmost) frames are
only deoptimized once they are returned to.
Drive-by: Print variable and total frame height in --trace-deopt.

The LinkageLocation currently consists of two fields, a bit_field and a
machine_type. The existing equality check only checked the equality of
the bit_field, which meant that a FP register location and a GP register
location could alias. I added a static {IsSameLocation} function which
checks that not just the bit_field but also if one of the two locations
at least has a subtype of the other. Note that we do not check for
type-equality because {CanTailCall} checks, which are the main user of
the LinkageLocation equality check, should pass even if the result types
are in a sub-typing relationship.

This CL consists of several preparatory steps for slices in Torque. Above all, it introduces a user-defined struct, torque_internal::Slice<T>, that performs bounds checking and returns references to elements in arrays. To enable this, several smaller changes were also made:
- Constructors of internal classes such as torque_internal::Reference<T> now require a special 'Unsafe' argument, making it clear that there be dragons.
- Struct methods are now declared during finalization. This allows instances of generic structs to have methods referring to the same struct. Previously, methods would be declared before the instance had been fully registered, leading to errors during type resolution. Furthermore, such methods were declared in a temporary namespace, that would then erroneously escape and lead to use-after-free issues.
- Instances of TypeArgumentInference were not running in the correct (Torque) scopes, leading to type resolution errors.
- The chain of ContextualVariable::Scope for any given ContextualVariable (such as CurrentScope) can now be walked, simplifying debugging.

This adds type reflection support to the {WebAssembly.Module.exports} as

With the added parenthesis from a previous CL, clang-format does a
decent job of formatting the nested ternary operator statement.

on the function, possibly triggering side-effects.
