fe45ddcc14 [dataview] Improve exception error messages
This CL makes the unoptimized DataView getter and setter methods
output the right function name when throwing an exception,
instead of a generic one.

It also contains a little drive-by cleanup of the Torque code
to keep it up to date with the language.

39e2d97bc4 [sfi] Replace start/end position with UncompiledData
Add new types for function data for SharedFunctionInfo, for uncompiled
functions. UncompiledData holds start/end positions, allowing us to
remove these fields from SFI. Uncompiled functions with pre-parsed
scope data now hold an UncompiledDataWithScope that has a pointer to
PreParsedScopeData -- this allows us to also remove the start/end pos
from PreParsedScopeData.

f9c4d0008f [explicit isolates] Move remaining roots to ReadOnyRoots
Moves STRUCT_LIST AND ALLOCATION_SITE_LIST into roots.h and adds access
to their associated maps using ReadOnlyRoots.

Also corrects the location of external_map, message_object_map,
empty_script, many_closures_cell, invalid_prototype_validity_cell and
builtins_constants_table which are not in RO_SPACE.

Finally this adds a convenience ReadOnlyRoots(Isolate*) constructor.

ff32ba8e54 [explicit isolates] Add ReadOnlyRoots
Adds a ReadOnlyRoots class trivially constructable from a Heap* or
Isolate* and which can be obtained from a any HeapObject which provides
access to roots objects that will always be in RO_SPACE. In the longer
term this object will be accessed via a global variable without
requiring an Isolate or using the memory address of a HeapObject to
infer it.

Moves the list macros in heap.h to roots.h and splits some of them into
two parts (read-only and mutable).

Convert cases of heap_object->GetHeap()->root_accessor() to
heap_objects->GetReadOnlyRoots().root_accessor().

7a3d92c132 [objects] Add instance types for hash tables
Adds a instance types for each HashTable subtype, rather than reusing
HASH_TABLE_TYPE. This allows us to check for these types by checking
the instance type directly, rather than by comparing against the map in
the root set.

Also, as a drive-by, do the same for SCRIPT_CONTEXT_TABLE_TYPE, and use
instance type checks rather than map checks for Context types.

This is a good general clean-up, but in particular is intended for
GetIsolate removal.

b9b4b8798f [wasm] Merge {WasmSharedModuleData} with {WasmModuleObject}
The {WasmSharedModuleData} struct was introduced to hold data common to
all wasm instances belonging to the same module. The idea was to keep
"internal state" separate from the JS-facing {WasmModuleObject}. Since
this objective has no real value, and we already store some internal
data on the {WasmModuleObject}, this CL merges these two objects.

b2abe2cf97 [wasm] Introduce specialized WasmCompileLazy frame type.
This makes the WasmCompileLazy builtin push a new WASM_COMPILE_LAZY
frame type. We can thereby remove the workaround to return a relocated
instance from the underlying runtime function. It also removes the last
remaining embedded code objects from {WasmCode} objects.

e0c3f6d6ca Disable embedded builtins
Embedded builtins have been regressing benchmarks incrementally as
more and more builtins were moved to the embedded blob. This has made
recognition and analysis of other possible performance issues more
difficult.

Let's disable embedded builtins until their performance is at an
acceptable level.

713e10c69e [wasm] Make {WasmExportedFunction} fields easier to reach.
This moves the internal fields on {WasmExportedFunction} objects from
being properties with private symbols to a separate structure instead.
The new {WasmExportedFunctionData} structure can hang off the underlying
shared function info which is created for each exported function. This
reduces the number of transitions, speeds up instantiation, and makes it
easier to reach them from generated code (in the future).

ab9e012426 Reland: [builtins] Patch self-references in constants table
Original CL: https://crrev.com/c/1018468

During code generation, we generate self-references (i.e. references to
the Code object currently being generated) as references to a temporary
handle. When the final Code object has been allocated, the handle's
location is fixed up and RelocInfo iteration fixes up all references
embedded in the generated code.

This adds support for this mechanism to the builtins constants table
builder. CodeObject() is now a new handle pointing to a dedicated
self-reference marker in order to distinguish between self-references
and references to undefined. In Factory::NewCode, we patch up
the constants table.

3ea1ad234c [typedarray] Implement TypedArray.p.sort using Torque.
This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:

When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.

The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.

Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

5728b3fbc5 [builtins] Separate species protectors for Array, TypedArray, Promise
Previously, there was one species protector for Array, TypedArray and
Promise. This CL splits the protector in three separate ones. This means
that invalidating one of them does not have negative performance
implications for the other ones.

9ab6621ac7 Reland "Reland "[heap] Move initial objects into RO_SPACE""
This is a reland of 6c68efac14

Updated Heap::CommittedMemory and related functions to iterate over all
spaces rather than including them manually which can lead to a space
being overlooked. Also adds a test to ensure this the case.
