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.

664158ab75 [test] Skip and mark slow tests
Many tests were already skipped in debug mode, but they kept running on CQ
which sets dcheck_always_on, probably equally slow.

Some other tests are marked as slow based on a recent run of the arm64 sim
trybot.

9c5a4abc18 [csa] Make LoadArrayElement generic.
Previosly, LoadArrayElement assumed that the array is a FixedArray.
The PropertyArray and WeakFixedArray pretended to be a FixedArray and
had static asserts about length offsets.

This patch make LoadArrayElement generic and uses a new LoadArrayLength
function to fetch the length of the array without hard-coding the length
offset.

9b0e4e132f [turbofan] Make typed optimization more powerful
This CL moves optimization capabilities from typed lowering to typed
optimization. In particular, this allows retyping of Speculative to
number optimizations depending on their input types. This can save type
checks if we know that inputs are already in SafeIntegerRange and uses
are truncating to 32bit integers.

This change recovers the performance lost to 31bit Smis on
Octane/crypto on x64:
32bit nosmis           avg 30,984.84 stddev 180.52

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.

ccd91026df PPC/s390: Print readable register names
Port de2681c1a8

Original Commit Message:

    This adds a {PrintRegister} method which prints the given register in a
    readable way (e.g. "eax", ... on ia32).
    This is currently only used in Liftoff. The {RegisterConfiguration}
    class has the same functionality, and I plan to make
    {RegisterConfiguration} also use the new {RegisterName} functions in a
    follow-up CL.

b28637b4fe [turbofan] Apply duct-tape to load elimination
Load elimination is running together with to dead code elimination, the
latter of which might eliminate allocations (in particular FinishRegion
nodes). These are treated as alias nodes by load elimination, and load
elimination does not immediatelly learn that a node has been disconnected.
This causes load elimination to access the inputs of dead code eliminated
nodes while resolving renames, which causes nullptr dereferences.

This CL modifies load elimination to not resolve to a nullptr alias but
simply stop before that.

2eab4de35d [parser] Further simplify ParseAssignmentExpression
This moves is_async and parenthesized_formals tracking out of the
ParseAssignmentExpression header. Instead we set flags on the parser for the
next arrow function: next_arrow_function_kind_ that defaults to kArrowFunction
and next_arrow_formals_parenthesized_ which defaults to false.

If we end up recognizing an async arrow head, we update
next_arrow_function_kind_ to kAsyncArrowFunction. If we detect (...) followed
by => or async(...) followed by => we set next_arrow_formals_parenthesized_ to
true. When we start parsing the arrow continuation we consume the values and
reset them to default for the next arrow function.

a04862021e [zone] Use 32kb instead of 1MB as high zone page size
It seems that allocating smaller pages is actually quite a bit faster than
larger pages, probably because they can be cached by malloc. Let's see what the
bots say.

In a follow-up I'll check whether the segment-pool is actually beneficial or
whether we should just remove it.

This also drops SegmentSize::kLarge as a way to make compilation deterministic.
Turns out that by now we need >8mb anyway, and the previous 1mb wasn't enough.
At the same time the compiler was fixed to not rely on virtual addresses of
zone objects anymore, and there's a bot checking whether the snapshot is
determistic.
