Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

One fundamental assumption of the wasm code GC is that code becomes
"potentially dead" at most once; if the ref counts drops to zero later,
it should be freed for real.
In the current implementation, it happens that code becomes potentially
dead, then becomes dead for real (it's removed from the set of
potentially dead code), and then we remove the last reference. At that
point, we re-add the code to the potentially dead code, considering it
for garbage collection again. This can lead to an endless loop.

This CL fixes that by remembering which code was already detected as
dead, and does not consider this code for another GC.
This requires freeing code via the {WasmEngine} such that the set of
dead code can be cleaned up.

Previously it was possible for this function to fall back to the
ArrayBuffer methods to free the memory in the cases where the
is_wasm_memory flag on the JSArrayBuffer is not propagated.
This is no longer the case, as we check for the actual allocation
so all memory allocated by the WasmMemoryTracker should be freed by
it as well. Rename the method to match the existing implementation.
