Currently this function requires the caller to hold a mutex for the
large page chunk hashtable and performs a hashtable lookup.
This patch adds a header sentinel field in each MemoryChunk. The field
is then used to distinguish large object slots from ordinary slots.

Class declarations support structured heap data that is a subtype of
HeapObject. Only fields of Object subtypes (both strong and weak)
are currently supported (no scalar fields yet).
With this CL, both the field list macro used with the C++
DEFINE_FIELD_OFFSET_CONSTANTS macro (to make field offset constants) as
well as the Torque "operator '.field'" macros are generated for the
classes declared in Torque. This is a first step to removing the
substantial amount of duplication and boilerplate code
needed to declare heap object classes.
As a proof of concept, and handful of class field definitions,
including those for non trivial classes like JSFunction, have been
moved to Torque.

This is purely a renaming change. The ES spec uses the term 'detach'

including method names and flag names, to match the spec.
Note that some error messages still use the term 'neuter' since error

Intrinsic changes:
- Rename %RawCast to %RawObjectCast and add error checking so that it
only applies to subtypes of Objects.
- Add %RawPointerCast, which is similar to %RawObjectCast but must be
used for all subtypes of RawPtr.
- Add %RawConstexprCast, which allows one constexpr to be be cast to
another at compile time. It translate to an appropriate static_cast
in the generated code
- Add %FromConstexpr, which handles most of the standard cases of
generating XXXConstant CSA nodes from constexpr constants. It uses
either SmiConstant, NumberConstant, StringConstant, IntPtrConstant
or Int32Constant, depending on the cast-to type generic <To> type.
- Add support for intrinsics that return constexpr results.
Cleanup:
- Turn FromConstexpr into a generic with two generic types, a <To> and
a <From> type. Most FromConstexpr can use the new %FromConstexpr
intrinsic rather than provide an explicit implementation.

This introduces a dedicated instance type for exception tags. The main
motivation is to reduce their footprint and getting rid of a temporary
workaround that used the {JSObject} type for this purpose.

This patch gives DescriptorArray its own visitor id and its
own layout that is independent from the layout of WeakFixedArray.
This allows us to use raw 16-bit integers for keeping track of
the number of descriptors (total, non-slack, and marked).
As a side-effect, we save one word per descriptor array on 64-bit.

We recently changed embedded builtins to be emitted as raw assembly
files during the build process in order to support MSVC (which doesn't
support inline assembly on x64). Ninja uses ml.exe / ml64.exe as the
assembler on all Windows builds (msvc & clang); these unfortunately
don't support large data streams well and can take over 5 minutes for
embedded.S.
With this CL we work around this by going back to inlined assembly for
clang Windows builds.

Adds a new field rare_data of type FunctionTemplateRareData to
FunctionTemplateInfo and moves 8 others which are unset on 90% of
FunctionTemplateInfo objects to this field.
Getters like prototype_template() are changed to GetPrototypeTemplate()
to indicate they're not trivial. The setters are replaced with static
methods (e.g. SetPrototypeTemplate) that take an Isolate and the
template object, since they can now perform allocation.

Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS
since that is called when we are compiling the native context independent SharedFunctionInfo
and the WasmModuleObject requires a native context. Instead save the members required to
create the object in the AsmWasmData and create it during module instantiation. Note:
since the Wasm module is an implementation detail for asm_wasm code and isn't exposed,
this doeesn't have semantic change for asm.js code.
As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated
struct. Some logic is also moved from module-compiler to wasm-engine to make the
seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.
