Changes:
- Add current global index argument to consume_init_expr.
- Inline DecodeGlobalInModule. Move the check for undefined global
indexes into into consume_init_expr. Note: This fixes a bug where the
index wasn't checked for nested global.get.
- Under --experimental-wasm-gc, allow global initializers to reference
already defined globals in the same module.
- Rename ModuleDecoderImpl::DecodeInitExpr -> DecodeInitExprForTesting.
Remove redundant "start" argument.
- Add tests for global initializers. Remove a redundant test.

The vast majority of operations increases the stack size by at most one.
Many opcode (e.g. all unary and binary operations) never grow the stack
at all. Still, for every "push" operation, they check whether the
storage for the vector that holds the stack values needs to grow.
This CL avoids those redundant checks by ensuring that there is space
for at least one more stack element before decoding each instruction.
By centralizing this check, we not only improve performance, but also
reduce code size significantly (~49 kB on x64 release).

A Wasm module's start function might be imported from JavaScript, and
as such might contain calls to Blink. For such a case, we must make
sure that an "incumbent context" is available. Usually, having any
JavaScript function on the stack is enough to ensure that; but in the
special case of async compilation, the "success" task is executed
directly from the event loop, so we have to manually enter a context.
Additionally, we need to ensure that such a start function's own context
is properly entered: in addition to setting it as the current context
on the isolate (as the function call sequence is doing), we have to
register it in the list of entered contexts, as if v8::Context::Enter
had been used.

When an Isolate in a multi-threaded environment is being debugged
and a thread does a Step Over (StepNext internally) one-shot
breaks are created in the code at the stack frame where the
StepNext occurred. However, if the stepped-over statement had
a function call and the called function (or some function that
it called) unlocked the Isolate (via a C++ function call) and
another thread then locked the Isolate, an ArchiveDebug would
be done which would save the fact that a StepNext is active and
the call frame depth of the StepNext. The one-shot breaks would
then be cleared to avoid stopping the now running thread.
When the original thread that did the StepNext relocks the Isolate,
a RestoreDebug is done which, seeing that a StepNext was active
calls PrepareDebug which assumes that the StepNext must be for
the current JS frame which is usually correct, but not in this
case. This results in the StepNext break actually occurring in the
function that called the C++ function not in the function where
the StepNext was originally done. In addition, the function where
the break now happens must necessarily be deoptimized if
optimized, and debug code and a source map table created if one
doesn't already exists though this is largely invisible to the
user.
Occasionally, a crash/core dump also occurs because the stack
guard is restored after the debugging environment is restored in
the RestoreThread code which can prevent the compiler from being
called to generate the source map table (for the incorrect
function) since the stack guard is another thread's stack guard,
and so might appear that the stack guard has been gone past so
the compiler is not called, resulting in there being no source
map table. But PrepareStep ends up calling the BreakIterator
(via the DebugInfo constructor) which assumes there is a source
map table so we get a crash.
The fix is to have PrepareStep to skip to the frame where the
StepNext was done before doing its thing. Since the only
PrepareStepcaller that requires a frame other than the current
frame, is RestoreDebug, a target frame parameter was added to
PrepareStep that's set by RestoreDebug and defaults to -1
indicating to use the current frame for all other callers.
While this made the order of the debug environment and stack
guard no longer cause an obvious problem, it still felt wrong
to defer restoration of the stack guard until after something
as potentially complex as PrepareStep might be called, so the
order of RestoreDebug and RestoreStackGuard calls were reversed.

This is a reland of 64caf2b0b2
Original change's description:
> [torque] refactor: use -tq only in filenames derived from .tq files
>
> This is to establish a naming rule for Torque-generated files:
> - If the file is called foo/bar-tq..., then it is derived from a
> file foo/bar.tq
> - Otherwise it doesn't belong to a specific .tq file.
>
> So far, we attached -tq to all Torque-generated file names, where it
> sometimes corresponded to a .tq file name and sometimes not.
> It is not necessary to add -tq to file names to indicate that they are
> Torque-generated, since they are already in a directory called
> torque-generated, and we always refer to them as
> "torque-generated/filename", so there is no confusion even though some
> files now have the same name as a corresponding hand-written file, for
> example factory.cc.

In atomic.wait we overwrote the register which stored the index,
without checking if it was still in use or not.

CallOrConstructWithArrayLike and CallOrConstructWithSpread builtins
expect only Smi in the array length field. This is true when we
have fast elements kind, but for dictionary mode we can have HeapNumbers
This cl fixes by moving the loading of length fields after the check
on elements kind to avoid loading length fields on dictionary mode
JSArrays.
