During Module::Reset(), the module is in an unstable state between the
change to SourceTextModule::code and Module::status.  Any reentrancy
between these points is problematic because the normal invariants about
the value of SourceTextModule::code in relation to Module::status do not
hold.

An allocation of the exports hash table in the middle of Module::Reset()
was causing reentrancy during this problematic time.  This change fixes
the issue by moving the allocation earlier in Reset() before any fields
are modified.

Retrieving the source position for a JavaScript stack frame is a
costly operation (it requires decoding the source position table).

The source position is usually retrieved twice, once for the line
number, and once for the column number.

This CL caches the resolved source position the first time around,
improving relevant stack trace serialization micro benchmarks by ~6%.

Even in the most basic case (the task queue only ever contains a single
element), this function triggers ~4KB in zone allocations. These
allocations are basically lost and can never be reused. Avoid this by
allocating inside a new temporary zone that is only alive during the
ComputeLoopState function call.

This reduces allocation size for the zone used during load elimination
from ~30KB to ~15KB when compiling a trivial for-loop example.

An alternative solution would be to switch to something similar to
SmallVector (which uses a statically-sized stack storage before
switching to heap allocations), but based on zones instead of malloc.

This change begins to implement the functionality described in
https://docs.google.com/document/d/1evHnb1uLlSbvHAAsmOXyc25x3uh1DjgNa8u1RHvwVhk/edit#
for investigating V8 state in crash dumps.

This change adds a new library, v8_debug_helper, for providing platform-
agnostic assistance with postmortem debugging. This library can be used
by extensions built for debuggers such as WinDbg or lldb. Its public API
is described by debug-helper.h; currently the only method it exposes is
GetObjectProperties, but we'd like to add more functionality over time.
The API surface is restricted to plain C-style structs and pointers, so
that it's easy to link from a debugger extension built with a different
toolchain.

This change also adds a new cctest file to exercise some basic
interaction with the new library.

The API function GetObjectProperties takes an object pointer (which
could be compressed, or weak, or a SMI), and returns a string
description of the object and a list of properties the object contains.
For now, the list of properties is entirely based on Torque object
definitions, but we expect to add custom properties in future updates so
that it can be easier to make sense of complex data structures such as
dictionaries.

GetObjectProperties does several things that are intended to generate
somewhat useful results even in cases where memory may be corrupt or
unavailable:
- The caller may optionally provide a type string which will be used if
  the memory for the object's Map is inaccessible.
- All object pointers are compared against the list of known objects
  generated by mkgrokdump. The caller may optionally provide the
  pointers for the first pages of various heap spaces, to avoid spurious
  matches. If those pointers are not provided, then any matches are
  prefixed with "maybe" in the resulting description string, such as
  "maybe UndefinedValue (0x4288000341 <Oddball>)".

This CL introduces generic Torque structs. Generics are grounded early in the Torque compilation pipeline, meaning that every instantiation of a generic struct with concrete types will be turned into a distinct StructType.

As an example, consider a Tuple of types T1, T2:

  struct Tuple<T1: type, T2: type> {
    const fst: T1;
    const snd: T2;
  }

which can be manipulated using generic macros, such as

  macro Swap<T1: type, T2: type>(tuple: Tuple<T1, T2>): Tuple<T2, T1> {
    return Tuple<T2, T1>{fst: tuple.snd, snd: tuple.fst};
  }

Currently there is no type inference for struct instantiation sites, so type arguments have to be provided explicitly:

  const intptrAndSmi = Tuple<intptr, Smi>{fst: 1, snd: 2};

We now have branchful decompression so this needs to be updated. Also,
the sxtw doesn't happen so it is not included in the regex.

I don't know why this didn't block the other CL's submission.

Also add tests for it.

Drive-by fix: Use ChangeInt32ToCompressedSmi since we have it

This will be used when the [[NewTarget]] is from another realm and
it's prototype is not an object.
