This is needed for the asm.js -> WASM pipeline. A single exported
function is exported as __single_function__, but we still want to see
the correct function name on the stack, so the underlying wasm function
has to carry the original name.

Unifies the approaches used for storing the specifier -> module mapping
and the module -> directory mapping, using std::unordered_maps for both
and storing them per-Context.
This requires adding a method to the v8::Module API to get a hash code
for a Module, but allows slimming down the API in return: gone are
SetEmbedderData/GetEmbedderData, along with the fourth argument
to ResolveModuleCallback.
Besides a simpler API, this allows d8 to get closer to the HTML loader,
which requires each Realm to have a persistent module map (though this
capability is not yet exercised by any tests).

The spurious failures were caused by the compiled module
template and its corresponding owning object getting out of
sync due to memory allocations (which may trigger GC)
between the points each were fetched.
Specifically, the {original} was first obtained; then a GC
may happen when cloning the {code_table}. At this point,
the {original}'s owner may have been collected, getting us
down the path of not cloning. When time comes to patch up
globals, we incorrectly try to patch them assuming the
global start is at 0 (nullptr), which in fact it isn't.
This change roots early, in a GC-free area, both objects.
Additionally, it avoids publishing to the instances chain
the new instance until the very end. This way:
- the objects used to create the new instance offer a
consistent view
- the instances chain does not see the object we try to
form. If something fails, we can safely retry.
- since the owner is rooted, the state of the front of the
instances chain stays unchanged - with the same compiled
module we started from. So the early belief that we needed
to clone is not invalidated by any interspersed GC.
This situation suffers from a sub-optimality discussed in
the design document, in that, in a memory constrained
system, the following snippet may surprisingly fail:
var m = new WebAssembly.Module(...);
var i1 = new WebAssembly.Instance(m);
i1 = null;
var i2 = new WebAssembly.Instance(m); //may fail.
This will be addressed subsequently.

The CL #39795 (https://codereview.chromium.org/2345593003 ) added MultiReturnSelect_f32/MultiReturnSelect_f64 tests.
Because those tests need 2 float point return registers and x87 only has 1 FP return register, Those tests failed at x87 port.
This CL skips MultiReturnSelect_f32/MultiReturnSelect_f64 tests for x87.

If an inner function only declares a variable but doesn't use it, Parser
and PreParser produced different unresolved variables, and that confused
the pessimistic context allocation.
This is continuation to https://codereview.chromium.org/2388183003/
This CL fixes more complicated declarations (which are not just one
identifier). For this, PreParser needs to accumulate identifiers used
in expressions.
In addition, this CL manifests FLAG_lazy_inner_functions in tests, so that
we get clusterfuzz coverage for it.

There were once plans to generate cross-context code with TurboFan,
however that doesn't fit into the model anymore, and so all of this
is essentially dead untested code (and thus most likely already broken
in subtle ways). With this mode still in place it would also be a lot
harder to make inlining based on SharedFunctionInfo work.

Found with libfuzzer. The length is automatically converted to int (thus
large sizes could become negative, even though they are legal "array sizes").
Besides that, the length is coerced to a SMI (which is an even tighter
constraint on 32-bit systems, where it limits the legal sizes to 2^30 - 1).
Add checks that the length of a dense array is below that threshold, and also
fail fast if a length that is provided obviously could not be the correct dense
length (because there isn't enough data left in the buffer to populate such an
array).

Previously this would result in applying trying to find a size modulo zero,
which causes SIGFPE. This approach was preferred over adding a default case
to preserve the ability of the compiler to detect unhandled switch cases
(within the valid range of the enum).
