- Implement RunMicrotasks in CSA to prevent a potentially large number
  of jumps between C++ and JS code while consuming te queue. Appears to
  provide a ~60% speedup in microtask-heavy code, which from limited
  testing appears to scale linearly.

  The code-stub microtask pump bails out to the old C++ microtask pump
  if it encounters a CallHandlerInfo microtask, and remains in C++ for
  the remainder of the queue (returning to the JS/stub implementation
  after the bailed out queue is exhausted).

- Add a variation of JSEntryStub which enters the new RunMicrotasks code
  stub.

- Add a new RunMicrotasks helper to Execution, which uses the
  RunMicrotasks entry stub.

A background task can now use GCTracer::BackgroundScope to
trace the time spent in the task. The time shows up in
--trace-gc-nvp output and in the runtime call stats for GC.

The destructor of GCTracer::BackgroundScope increments the
corresponding counter in heap()->tracer()->background_counter_,
which is protected by a mutex.

The GCTracer::Stop function fetches background_counter_ items
into the global scope and into the runtime call stats.

The return type of stores is void according to the WebAssembly spec.
In wasm-opcodes.h, however, the return type of stores was set to the

issues which were caused because now there exist opcodes with a return
count different to 1.

This is to avoid calling AssembleTailCallBeforeGap and AssembleTailCallAfterGap
directly where possible (so making the tests less dependent on the code generator
interface when we're not directly testing it). It also makes sure that the
instruction we pass to AssembleTailCallBeforeGap and AssembleTailCallAfterGap is
indeed a tail call, with the immediate argument that specifies the stack delta.

This is to prepare for padding arguments for arm64 JSSP removal. We will need to
store padding in AssembleTailCallAfterGap, which will need the information from
a TailCall instruction.

Separates restoring iterability from sweeping a page. Since the set
of pages where iterability needs to be restored is small, it is
possible to wait and block for the task to finish if necessary.

A follow up change can now remove the fragile logic for delaying
unmapping of pages since it is guaranteed that no background task
keeps a reference to a page for restoring iterability.

Add support for matching '(x & mask) == mask' when mask has a single bit set,
and translate this into a tbnz instruction. This patch only does this for 32-bit
operations, we can port it to 64-bit operations as a follow-up if we find
matches.

This transformation mostly touches the snapshot where we get ~120 hits. This pattern can
also show up in JavaScript when introduced by the EffectControlLinearizer pass.

The existing object materialization in the deoptimizer has the following problems:

- Objects do not necessarily verify during materialization (because during the
  depth first walk we might have inconsistent objects).

- Stack can overflow (because we just materialize using recursive calls).

- We generalize object fields.


This CL re-implements the materialization algorithm to solve this problem. The
new implementation creates the objects in two steps:

1. We allocate space for all the objects. In general, we allocate ByteArrays
   of the right size. For leaf objects that cannot participate in cycles,
   we build and initialize the materialized objects completely.

   For JS objects, we insert markers into the byte array at the positions
   where unboxed doubles are expected.

2. We initialize all the objects with the proper field values and change the
   map from the ByteArray map to the correct map. This requires some sync
   with the concurrent marker (Heap::NotifyObjectLayoutChange).

   When initializing the JS object fields, we make sure that we respect
   the unboxed double marker.

This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

The deleted lines are unnecessary, but somehow still managed
to make their way in.
