      [arm64] Update BuiltinContinuation frames for jssp alignment. · a63f045c
      Georgia Kouveli authored 
      Adds some necessary padding to ensure the frame is 16-byte aligned.
We don't yet consider the bailout state, which will be handled separately.

This patch also improves the code generated for ContinueTo*Builtin* stubs.

Finally, it adds a test that checks the return value for Array.map in
the case where a LAZY deopt results in a topmost builtin continuation
frame - this is easy to break if the padding for the result is done
incorrectly in NotifyBuiltinContinuation, but was not detected by existing
tests.

      [wasm] [debug] Implement calling imported wasm functions · c39c6eba
      Clemens Hammacher authored 
      The interpreter was not able to call imported wasm functions (hitting
UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is
signature-specific. It has JS linkage and receives the wasm code object
to call and a buffer containing all arguments (similar to the
interpreter entry). It loads all arguments from the buffer and calls the
given code object.
The c-wasm-entry code objects are cached per instance, such that we
only create them once per signature.

These wasm entry stubs will also allow us to call back to compiled code
from the interpreter, which we might want to do to reduce the slowdown
of executing wasm for debugging.
