When compiling a script with lazy inner functions, we now know the
scopes that those inner functions belong too and need to save this
information on the inner function itself (as enclosingScope). This patch
makes that process more explicit in JSScript initialization so we can
better reason about error / OOM paths.

Use an ExitScope similar to to XDRScript for more consistency.

Compute this flag directly from BytecodeEmitter data structures instead
of needing to access the partially initialized script while setting its
own flags.

This removes the redundant set of TreatAsRunOnce which is instead set by
CompileOptions before we start compiling. The IsModule flag is now set
directly similar to IsForEval.

Debugger or OOM errors can close the generator after JSOP_ASYNCAWAIT enqueued
a promise job for AsyncFunctionResume. Change AsyncFunctionResume to handle
this case and also try to reject the result promise with the pending OOM error
if possible.

- Remove nullptr checks for `calleeTemplate` because it can't be null for
function frames.
- Always skip over `InterpretGeneratorResume` to ensure baseline sees the same
number of debugger enter-frame events as interpreter.

They're only used in CodeGenerator.cpp so we can now move some of the helper

Bulk memory operations can be enabled at the same time Cranelift is, in which
case partial initialization of elements/segments/etc. implementation is
statically implemented, but dynamically controlled by wasmBulkMemoryOps().
Cranelift doesn't implement bulk memory operations yet, so wasmBulkMemoryOps()
returns false, while the static behavior is there. Thus, we have to temporarily
disable partial initialization tests when running with Cranelift. This will go
away when Cranelift supports bulk memory operations.

In bug 1264235 we have some indication that observed bugs with the
startup cache might have been resolved, but we don't really know
until we collect data. Collecting these stats will give us the
ability to have more certainty that the startup cache is functioning
correctly in the wild.

The tab_test() would compile and link the module for every element of
the result array, but the module should be invariant for the result
array, so this is not necessary.

Our bounds checking is a little too stringent - we disallow
zero-length operations at the edge of the memory, table, or segment,
but the spec allows that, a behavior inherited (from active segments)
from the MVP. It's also a natural consequence of how we handle bounds
checks for non-zero length operations.
So loosen the tests slightly and adapt the test cases, testing both at
the edge of the table/memory/segment and one past that. In the former
case we allow the operation, in the latter not.
