The previous code assumed that trap handling was a global concept, defined
by function trap_handler::UseTrapHandler(). This CL does the first step
in changing the decision to be specifiable at a module level.
Therefore trap_handler::UseTrapHandler() is replaced by
trap_handler::IsTrapHandlerEnabled(), and communicates if compilation
supports the use of trap handlers (but still allowing the use of
bounds checking on memory accesses).
It then refactors the classes ModuleEnv and WasmCompiledModule to have
a field "use_trap_handler" that specifies if traps should be used for
the memory accesses in the module being compiled.

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

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.

The existing object materialization in the deoptimizer has the following problems:
- Objects do not necessarily verify during materialization (because during the

- 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

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.
