There are only very few custom compiled IC handlers left that go in there, and for each compiled handler we only have 1 cache hit on top25; maximally saving 60ms over 33s. Additionally we'll migrate the remaining handlers to data-driven handlers anyway. Let's try to remove this code.

BigInt is a new primitive type of arbitrary precision integers,
proposed in https://tc39.github.io/proposal-bigint.
This CL introduces a corresponding instance type, map, and C++
class to V8 and adds BigInt support to a few operations (see the
test file). Much more is to come. Also, the concrete representation
of BigInts is not yet fixed, currently a BigInt is simply a wrapped
Smi.

Introduce a proper empty_descriptor_array, which has the proper layout
(length is 2 and the two fields are set properly). Also add a special
EnumCache class and a matching empty_enum_cache. The contract now is
that we only need to check the EnumLength on the map to know whether we
are allowed to use the enum cache. This greatly simplifies the handling
of the enum cache (and also the descriptor arrays), especially for the
future work on optimizing keyed access via the enum cache indices.

This is useful when tests that belong to the same area have different

'cctest/test-run-wasm*' and 'cctest/test-wasm*'. With this CL it is
possible to specify the selector 'cctest/*wasm*' to run them all.

The interpreter was not able to call imported wasm functions (hitting
UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is
signature-specific. It has JS linkage and receives the wasm code object
to call and a buffer containing all arguments (similar to the
interpreter entry). It loads all arguments from the buffer and calls the
given code object.
The c-wasm-entry code objects are cached per instance, such that we
only create them once per signature.
These wasm entry stubs will also allow us to call back to compiled code
from the interpreter, which we might want to do to reduce the slowdown
of executing wasm for debugging.
