1ad0cd560e Separate DescriptorArray from WeakFixedArray
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.

8c1248932e [builtins] Emit builtins as inline assembly on windows clang builds
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.

b0b5eae096 [objects] Shrink FunctionTemplateInfo
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.

ccd8073c7b [AsmJs] Avoid allocation of WasmModuleObject until instantiation.
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.

This cl updates:

collected
2. Checks if feedback vectors are valid before using then when
creating closures
3. Runtime profiler to only tier up functions with feedback
4. Interpreter entry trampoline to check for feedback vector before
using it.

00ffe4a613 [torque] enable multiple inheritance from Torque-generated assemblers
This enables more seamless interop between Torque and CSA:

Since CodeStubAssembler can now inherit from the Torque base namespace,
macros defined in the base namespace can be used in CodeStubAssembler
macros, even without qualification.
At the same time, macros in the base namespace can refer to
CodeStubAssembler macros. The only new limitation is that types defined
in code-stub-assembler.h cannot be referenced in the signature of macros
defined in the base namespace, since this would produce a cyclic header
dependency. A work-around for this woud be to put such types (like int31
in this CL) into a separate header included by both. I (mis-)used
code-assembler.h for that.
Another side-effec is that types and enums defined in CodeStubAssembler
have to be accessed in a qualified way from Torque.

Other assemblers can now inherit from their Torque equivalent, so
porting macros into the corresponding Torque namespace doesn't require
any change to the existing use-sites.

To avoid C++ ambiguities, the Torque-generated assemblers must not define
anything also defined in Code(Stub)Assembler. This includes the type
aliases for TNode, PLabel, ...
My workaround is to qualify everything in the generated C++.

As a drive-by fix, I had to change the formatter to avoid a situation
where it doesn't compute a fixed point: putting a keyword at the
beginning of a line removes the '\s' in front of it, so I replaced that
with '\b'.

d469fec064 [ptr-compr] Introduce EmbedderDataArray
for storing embedder data in native context. We can't use FixedArray because
with enabled pointer compression it would not be possible to fit raw aligned
pointer into 32-bits of a tagged value so we will need to store both tagged
and raw data in this array and therefore custom visitor is required.
