In TurboFan, context specialization is an optimization that tries to
either replace the load of a value from the context with a constant,
or if that can't be achieved, at least reduce the hops up the
context chain by starting a walk to the required depth from the
first constant context that it can reach.
Currently, this optimization is performed by looking into the
heap during a reducer pass. With fully concurrent TurboFan, we
need to instead gather information about contexts we may want
to perform this optimization on during serialization.
This CL adds functionality to the serializer to recognize and
model operations that affect the context register. We add to the
hinting structure already used by the serializer. There is
a new type of hint: a VirtualContext. This is a tuple consisting
of a handle to a Context, and a distance field that indicates how
far away in a to-be-realized chain this VirtualContext sits from
the context in the handle. For example:
bytecode stream:
...
CreateBlockContext
...
After a block context is created, the accumulator now contains
a VirtualContext Hint with a distance of 1 from any context hints
that we are keeping track of in the current context register.

Perform a best-effort check for module context and provide an
appropriate error.
As seen from the import-blah-script.js test, we could have invalid
import expressions in a script context that could result in an error
saying "Cannot use import statement outside a module" which isn't
the ideal error because the error is an incorrect import
expression.
But, when the developer changes to a module context, the
correct error is thrown.
To fix this, we'd have to refactor and call ParseImportDeclaration,
and then throw an appropriate error, which seems like a lot of
overhead for not enough gain.

This CL refactors the type-checking for br_table instructions.
Originally, we iterated over all targets of br_table and checked
if the values on the stack match the types expected by the
target's signature. However, this caused problems with type
checking unreachable br_table instructions where some stack
values are unavailable. According to the anyref proposal, the
expected type of br_table is the greatest lower bound of
all its targets. With the existing implementation, the expected
types were the types of the first target.
With this CL, we first calculate the expected types of br_table,
and only then inspect the stack if matching values are available.

To correctly fuzz the behaviour of optimized code and ICs we need to
allocate feedback vectors. So for the configurations testing these we
should turn off lazy feedback allocation.
It is also good to fuzz without lazy feedback allocation on other
configurations to flush out any other issues. So we also fuzz this with
0.35 chance. We also fuzz aggressive lazy feedback allocation (allocate
feedback vectors on first branch / return) with 0.05 chance to test
corner cases related to lazy feedback allocation.

We currently use the class name “JSValue” for JSObjects that wrap
primitive values. This name is a common source of confusion. This patch
switches to a name that’s more clear.
In addition to manual tweaks, the patch applies the following mechanical
global replacements:
before | after
--------------------------------|--------------------------------------
if_valueisnotvalue | if_valueisnotwrapper
if_valueisvalue | if_valueiswrapper
js_value | js_primitive_wrapper
JS_VALUE_TYPE | JS_PRIMITIVE_WRAPPER_TYPE
JSPrimitiveWrapperType | JSPrimitiveWrapper type
jsvalue | js_primitive_wrapper
JSValue | JSPrimitiveWrapper
_GENERATED_JSVALUE_FIELDS | _GENERATED_JSPRIMITIVE_WRAPPER_FIELDS

We have a global test/OWNERS that has "file://COMMON_OWNERS".
This CL removes redundant OWNERS files in test/ subdirectories and
removes redundant entries from OWNERS files we need to keep for
special per-file entries.

... in addition to existing [Heap]Object::IsXXX().
The idea is to use these getters in hot C++ code since passing isolate
explicitly makes it trivial to compute isolate root value and reduces
the C++ code size.
For full-pointer mode the unused isolate argument will be optimized
away by the compiler, so full-pointer mode should not be affected
in any sense.
