It's a growing weak array which also has an API for marking slots empty (those
will then be filled before growing the array again).
This is a more efficient implementation than the corresponding feature in
FixedArrayOfWeakCells, because we chain the empty slots together.

This CL adds local const bindings. This means that instead of
generating TVARIABLEs for variables, we can generate simple TNodes.
Example:
macro FooBar(): {
const kSomeSmi: Smi = 10;
...
}
This CL also enforces that variables with a constexpr type are bound
using 'const' and not 'let'.

SharedFunctionInfos store their original function literal's id. This is
also their index in the Script's SFI list.
The function literal id is only needed for lazy compilation and live edit,
and access only has to be fast in the former. So, we can move the SFI
function literal id field to UncompiledData, and if patching with live
edit, or discarding compiled code, we can perform a slower linear search
through the Script's SFI list.
This is a reland of
1) https://chromium-review.googlesource.com/1082480 and
2) https://chromium-review.googlesource.com/1128854
the differences being:
1) caching the literal id on UncompiledData rather than always linearly
searching the SFI list, and removing the unused runtime-liveedit.cc
file instead of fixing it to support this change.
2) clearing padding on UncompiledData now that it has 3 int32 fields,
making its end unaligned on x64.

The code under test is handling of multi-return values in TurboFan and
hence actually independent of WebAssembly. The only reason to generate
WasmCode is in order to use the WebAseembly linkages. This changes the
generated code to have {STUB} kind instead of {WASM_FUNCTION} kind to
avoid having stack checks in the generated code which would require a
proper WasmInstanceObject to be allocated.
