      Milad Farazmand authored 
      Port c0eee179

Original Commit Message:

    ROL will be optional operator as arm, arm64 only have ROR.

    The reason for this CL is inefficient Wasm codegen for 64-bit
    left-rotation.

      [wasm-simd] Remove interpreter tier of SIMD tests · 3c400825
      Deepti Gandluri authored 
      As per the all-hands a couple of weeks ago, the interpreter will
be removed soon. Remove running tests on this tier, so we no longer
put effort into maintaining tests for this tier.

      [debug] Don't crash when breaking on entry to functions with heap vars · 3c20dfed
      Seth Brenith authored 
      Any function with heap-allocated variables starts by creating and
pushing a new context for its execution. When entering the debugger due
to the stack check in the beginning of InterpreterEntryTrampoline, the
function has not yet had a chance to push that new context. The code in
ScopeIterator currently assumes that any function which needs a context
already has one by the time the debugger attempts to iterate scopes, but
in this case that assumption is invalid, which can cause a null deref.

This change introduces a new function ScopeIterator::NeedsAndHasContext
to replace previous calls to current_scope_->NeedsContext(). This new
function checks for the case where the current scope matches the closure
scope but the context matches the containing context for the function,
which implies that the function has not yet pushed its own context.
