The bot that runs gcmole was failing before
https://crrev.com/c/1789707 because the test file was missing.
It returned with exit status 0 anyway though. After fixing the
original fault, this CL ensures that the gcmole tests also
trigger an error on the bot(s) if they fail.

It is not recommended to define type alias in C++ header file. cctest defines
type alias `using Label=CodeAssemblerLabel` in anonymous namespace under
namespace `v8::internal::compiler` in test-code-assembler.cc. This is fine
because this type alias is expected to take effect only in this .cc file. But in
jumbo build, multiple source files are combined as a single one, and the
previous `Label` type alias could shadow definition of `Label` from other header
file (for example, v8/src/codegen/label.h which is included by another .cc file)
This is totally unexpected and triggers bad class layout and accessing in the
latter .cc file for the places where `Label` is referenced.
This change fixes cctest from Windows ARM64 jumbo build, but it applies to
other architectures too.

ScopeIterator was changed to re-parse the whole script instead of

position of generator functions to correctly identify their
closure scope. This is no longer necessary and this CL removes
the manual source position adjustment.

Reland after disabling the test getting deadlocked with '--gc_stress' flag.
The CL was reverted because of the 'wasm/grow-shared-memory' test from

This CL makes scopes in class heritage position skip their outer class

Original message:
The implementation on wasm-bigint has been done, as far as I can tell.
There are no spec tests yet, only an out-dated copy of the original
spec tests which don't pass anymore. Therefore I disabled all the tests
for now and created a tracking bug at https://crbug.com/v8/9673.

Node now requires gcc >=6.3, and we do not test on gcc <5.4 any more.
Thus remove a special case for gcc <5.

This makes sure no underlying ArrayBuffer is reserved for modules that
don't declare a module. For the case where a memory is declared but the
initial size is 0, we still reserve a buffer in case of trap handlers.

This reduces the size per runtime stub slot by using the same sequence
we plan to use for far jumps.
Note that alignment is not an issue here, since runtime stub slots are
never patched.

The inferred name in the function literal might not be as accurate as the one
already on the shared function info, so use the existing one instead.
