1. On Android, Skips mjsunit tests depending on setting LC_ALL env var.
2. With the cherrypick from ICU, locale "C" will no longer be
canonicalized into "en-US-POSIX" since that is not part of a
registered canonicalization. So on OS which there are no LANG,
LC_CTYPE or LC_MESSAGE env vars, we need to also map that
fallback locale "C" to "en-US".

This will allow the devtools UI to display private fields on the scope
panel.
Instead of extending GetInternalProperties, we expose a separate
GetPrivateFields method on the debug interface. This allows us to do
better type checking, for example, we can directly cast to a
v8::Private as this can only contain private fields.
This also allows us to have better constraints on the input type --
v8::Object, as opposed to a v8::Value.
The KeyAccumulator is extended to collect private names for the
PRIVATE_NAMES_ONLY PropertyFilter.

When calling the `bitmap(chunk)` method of the various *MarkingState accessors
we would receive a raw `Bitmap` pointer which does not tell you if accesses to
markbits should be made atomically or not. As a result, we would default to
doing atomic operation when in fact it may not be necessary.
Here we're introducing a templated `ConcurrentBitmap` class that wraps
operations done on the markbits and allows them to be made non-atomic.
Additionaly, some of the `Bitmap` methods were only used to verify the heap and
in the tests so they do not need atomic implementations. Using them in a
concurrent context should now fail to link to make sure they're not mis-used in
the future.

When calling a known function from optimized code, where the number of
actual arguments does not match the number of expected arguments,
TurboFan has to call indirectly via the arguments adaptor trampoline,
which creates an argument adaptor frame underneath the activation record
for the callee. This is done so that the callee can still get to the
actual arguments, using either
1. the arguments object, or
2. rest parameters (to get to superfluous arguments), or
3. the non-standard Function.arguments accessor (for sloppy mode
functions), or
4. direct eval(), where we don't know whether there's a use of the
arguments object hiding somewhere in the string.
However going through the arguments adaptor trampoline is quite
expensive usually, it seems to be responsible for over 60% of the
call overhead in those cases.
So this adds a fast path for the case of calling strict mode functions
where we have an arguments mismatch, but where we are sure that the
callee cannot observe the actual arguments. We use a bit on the
SharedFunctionInfo to indicate that this is safe, which is controlled
by hints from the Parser which knows whether the callee uses either
arguments object or rest parameters.
In those cases we use a direct call from optimized code, passing the
expected arguments instead of the actual arguments. This improves the
benchmark on the document below by around 60-65%, which is exactly
the overhead of the arguments adaptor trampoline that we save in this
case.
This also adds a runtime flag --fast_calls_with_arguments_mismatches,
which can be used to turn off the new behavior. This might be handy
for checking the performance impact via Finch.

Template objects should be cached after they are first created and reused on
subsiquent calls to tag functions. Currently these cached objects are stored
on the feedback vector, which has appropriate lifetime, however with bytecode
flushing the feedback vector could be cleared when the bytecode is flushed,
causing the template object to be dropped.
In order to retain the cached template objects in the face of bytecode flushing,
this CL adds a weakmap for each native context that is (weakly) keyed by
shared function info, and holds a linked list of cached template objects
associated with that shared function info, indexed by feedback vector slot id.
Misses will check this weakmap, and if no entry is found, a new template object
is created and added into this weakmap alongside the feedback vector.

This merges all the possible targets for 'member expressions' previously
parsed in ParseMemberExpression into ParsePrimaryExpression; since that's
not independently used anyway. This will make it faster since we don't
need to go through unnecessary branches before ParsePrimaryExpression on
the fast path, *and* it will make the binary smaller since
ParseMemberExpression is inlined but ParsePrimaryExpression is not. It
saves 4kb. Yay :)

Do not leak handles to the outer scopes from inspector methods.
Add `SealHandleScope`s to the tests and the d8 binding, and
`HandleScope`s in the places in the inspector source where
handles are actually used.

When using a shared WebAssembly.Memory, always try to reserve up to the
maximum to avoid having to move the buffer. If after multiple retries
it is not possible to reserve the maximum, fall back to initial size
reservation.
- Add new methods to allocate a Shared WebAssemblyMemory.buffer
- Use these to reserve upto the mazimum for a Shared WebAssembly.Memory
- Cleanup js-api so actual allocation is done inside the constructor

Implement the ReturnCall functionality for the interpreter.
Note that some tests have had to be deferred to the implementation
of ReturnCall for TurboFan.
