8c057f1736 [bigint] Define V8_ADVANCED_BIGINT_ALGORITHMS everywhere
It was previously only passed to compilation units in src/bigint/,
but inconsistencies arise when it's not passed to other compilation
units that #include src/bigint/bigint.h.

Fixed: chromium:1233397

fb0a2ea25e Revert "Reland "[build] Add V8-specific dcheck_always_on""
This reverts commit 67960ba110.

Reason for revert:
This has been properly fixed by https://crrev.com/c/3053740.
Now dcheck_always_on already defaults to false for subprojects
like V8 and no other switch is required. The switch didn't fully
work anyways due to https://crbug.com/1231890.

Avoid callers operating on raw top/limit where possible and provide

This is actually related to the refactoring suggest in v8:11958 in
that it cleans up the call sites a bit but doesn't go further than
that.

92bfb63cac [build] Separate out inspector as a shared library
This makes src/inspector:inspector into a v8_component producing a
shared library in component builds. To enable this, all of its exported
are now marked with V8_INSPECTOR_EXPORT.

This also inverts the dependency between src/inspector:inspector and
:v8_base_without_compiler, and instead makes d8 and some tests depend on
inspector rather than getting it via v8.

As a result, the no_check_targets exclusions list in .gn is reduced.

Ultimately embedders like chromium should depend on :v8 and optionally
src/inspector:inspector, but to allow that transition to occur, this
renames :v8 to :v8_lib and introduces a new :v8 which depends on v8 and
inspector. Once all embedders have changed to reflect the new structure,
this part can be reverted.

git grep -l <pattern> | grep -v base/vector.h | \
  xargs sed -i 's/\b<pattern>\b/base::<pattern>/
with lots of manual clean-ups due to the resulting
v8::internal::base::Vectors.

#includes were fixed using:

227e90188b [ext-code-space] Add CodeDataContainer::code field and friends
... behind the v8_enable_external_code_space build flag.

This is a first CL in a row of CLs that will make CodeDataContainer
the only type of objects that could contain references to Code objects
(besides the Code objects embedded into the generated code).
Eventually these changes will allow us to move Code space out of the V8
heap cage.

This CL adds |code| field to ensure that CodeDataContainer keeps the
respective Code object alive and |code_entry_point| field that contains
cached value of the code().InstructionStart().

9444600b5b [build] Move FunctionTemplateInfo methods out of objects.cc
This moves all of the FunctionTemplateInfo code into templates.cc and
removes the inline keyword from BreakAtEntry which is moved out of
templates-inl.h. As a result templates-inl.h no longer depends on
shared-function-info-inl.h. This in turn uncovered lots of other missing
includes which are now in place.

82b673bcbc Fix counting ignition dispatches
The flag --trace-ignition-dispatches has been broken for a long time,
since it was not designed to work with bytecode handlers that are
generated ahead of time by mksnapshot. This splits the existing
--trace-ignition-dispatches logic into two separate parts:

1. A gn argument which instructs mksnapshot to include dispatch counting
   in the bytecode handlers, and ensures that the Interpreter allocates
   the array of counters, and
2. A runtime flag which enables the ignition-statistics extension which
   implements the JS-accessible function getIgnitionDispatchCounters().

dc3f7f81c9 [wasm] Implement EvaluateInitExpression
So far, initializer-expression evaluation was tied to setting global
values. We now need it to operate independently of globals, so that we
can implement new constant expressions like struct.new, which need their
arguments to be computed before they can be initialized.

Changes:
- Move type computation of WasmInitExpr into WasmInitExpr::type.
- Fix WasmInitExpr::type kRttSub case for rtts without depth.
- Introduce InstanceBuilder::EvaluateInitExpression().
- Rename InstanceBuilder::GetRawGlobalPointer() ->
  GetRawUntaggedGlobalPointer().
- Simplify InstanceBuilder::InitGlobals using EvaluateInitExpression().
- Introduce ValueType::is_numeric.
- Add Simd128(byte*) constructor.
- Introduce WasmValue::CopyTo() for numeric types.
