2497023acb Refine the type of Context to NativeContext around JSObject
This updates the type of contexts to NativeContext instead of Context,
namely on GetFunctionRealm(), GetCreationContext(), and
JSGlobalObject::native_context.

They should be semantically NativeContexts, but the return type hides
the underlying NativeContext, and causes its user to cast the context
to native.

648ba1f7dd Defer inferring language mode for PropertyCallbackInfo
This cl: https://chromium-review.googlesource.com/c/v8/v8/+/1421077
changed the implementation of SetProperty to infer the language mode.
Language mode is only required when there is an error to decide if we
have to throw an error or not. However we used to compute language mode
eagerly for PropertyCallbackInfo. This causes regressions in some
benchmarks. This cl changes it by deferring it further by computing
it only when it is actually required.

ad3546ab74 Explicitly store the code layout in CodeDesc
This is an initial step towards clarifying the layout of the
instruction area. As follow-ups, we should remove additional
safepoint and handler table offset parameters, and perhaps alter
Code::safepoint_table_offset (handler_table) semantics to always
contain a real offset and avoid the magic 0 signifying nonexistent
tables.

27a71e94f9 MIPS32: Configure heap for snapshot with maximum reserved memory.
MIPS32 doesn't have constraint for maximum code range or maximum PC
relative code range, and allocation of kMaxPCRelativeCodeRangeInMB
memory results in OOM failure from allocator.

This patch also skips verifying transitive builtins for 64-bit MIPS
because it doesn't have implemented pc-relative calls and jumps yet.

97cdf35f4a [wasm] Implement table.drop
The table.drop bytecode "drops" the backing storage for an element
initializer. In the V8 implementation, this is a nop, other than
updating a per-instance boolean array so that two drops of the same
segment or a drop of an active segment will trap.

This is implemented with inline code in TurboFan in order to be symmetric
to memory.drop, but could as easily be a runtime call to be supported in
Liftoff.

9f90c8dc43 [wasm] Force GC earlier to avoid running OOM
We currently trigger a GC when creating a module while the remaining
uncommitted code space is below 32MB. For bigger modules, this is not
enough. Instead, make this limit relative: Trigger GC if we fall below
50% of the available code space, and re-adjust this limit after each GC
to avoid repeated GCs that do not free anything.

f323a5f415 [nojit] Add a kCallBuiltinPointer call kind
Currently, Torque's builtin pointers store a Code target underneath and
callsites generate a kArchCallCodeObject opcode. When embedded builtins
are enabled, the call thus first calls the on-heap trampoline, which
finally jumps to the target off-heap builtin code.

This will no longer be possible in jitless mode, since on-heap code must
not be executable.

As a step towards changing the way builtin pointers are called
(function pointers will hold the builtin index as a Smi, and callsites
look up the off-heap target address and jump there), this CL adds a
dedicated opcode for builtin pointer calls to the compiler pipeline.

The calling mechanism itself is unchanged, changes there will happen
in a follow-up.

Drive-by: rename 'FunctionPointer' in torque/ to 'BuiltinPointer'.

4084185b3c [wasm] Implement memory.init and memory.drop
`memory.init` copies bytes from a passive data segment to linear memory.

`memory.drop` is an instruction that informs the wasm VM that the instance no
longer needs access to the passive data segment.

Information about the passive data segments, including their contents, length,
and whether they are dropped, is stored in the `WasmInstanceObject` as primitive
arrays.

ed3d647284 Reland "[code-comments] Put code comments into the code object"
This is a reland of e774cffe2b

This reland disables a test as v8:8548 is blocking it, which was
broken by a recent CL. CQ did not catch this because the merge-base
CQ used did not yet contain the CL that caused v8:8548.

2de45f214c [heap] adjust kMaxRegularHeapObjectSize on ppc64le
This is to address the first issue reported on v8:8453

Page::kPageSize is 524288
MemoryAllocator::GetCommitPageSize() returns 65536 on ppc

ObjectEndOffsetInCodePage() returns 458752
ObjectStartOffsetInCodePage() returns (65536 + 65536) => 131072

Therefore, memory = 327680, which is less than
kMaxRegularHeapObjectSize(507136), which causes the DCHECK to fail.

a31ffef811 [heap] Take expected OS page size into account for kStoreBufferSize
This CL fixes allocation size alignment violation when allocating store buffer.
If the actual CommitPageSize happens to be bigger than kMinExpectedOSPageSize
we will have a bit of memory wastage but that's a fair trade-off for having
fast store buffer overflow check in write barriers.
