Change GetHeap() in set methods to Heap::FromWritableHeapObject() since the object can't be read-only if set is being called on it. Also use the non-isolate form of set_the_hole to remove one GetIsolate().

Instead of creating a separate code object per exported function, we can share the code per signature, and load the function index from the {WasmExportedFunction} object which is being passed as an argument anyway. This greatly reduces instantiation time for modules with a lot of exports. As a next step, we could even share the code across instances, or (with more work) across isolates.

This is a clean-up to completely remove the Heap accessors for roots accessible via ReadOnlyRoots. Where previously ReadOnlyRoots called the Heap accessor, now it accesses the roots array directly using the root index (since ReadOnlyRoots is a friend of Heap). Also clean up several cases where private Heap accessors were still being used by Heap and its friends.

RegExp builtins were the first to be ported to CSA roughly two years ago. Back then, we weren't really aware of issues surrounding code size and CSA inlining, and thus some of these builtins were bigger than they should be. This CL adds a few new helper builtins and removes inlined calls to SubString, RegExpExecInternal, and StringAdd. It significantly reduces the size of affected builtins. Minor performance regressions due to call overhead are expected. Before: TFS Builtin, RegExpReplace, 20008 TFS Builtin, RegExpSplit, 17340 TFS Builtin, RegExpMatchFast, 17064 TFJ Builtin, RegExpStringIteratorPrototypeNext, 12862 After: TFS Builtin, RegExpReplace, 5067 TFS Builtin, RegExpSplit, 6329 TFS Builtin, RegExpMatchFast, 8164 TFJ Builtin, RegExpStringIteratorPrototypeNext, 6652 Bug: v8:5737 Change-Id: I1c077a084da85bb73c0c5adb7118b941f488e0ec Reviewed-on: https://chromium-review.googlesource.com/1127796Reviewed-by:

When calling an import which is an exported wasm function, the interpreter needs to look through the jump table to find the actual code object. We already had that logic for indirect calls, but it was missing for imported calls.
