The dotAll flag changes behavior of the dot '.' character to match every
possible single character instead of excluding certain line terminators.

The implementation is staged behind --harmony-regexp-dotall.

(see https://codereview.chromium.org/2757263002).
This CL also changes source positions, safepoints and back edges to use
the same format. This allows easier matching.

This CL cleans up a few things:
- It removes two dead declarations: WasmMemoryObject::Grow and
  wasm::GrowInstanceMemory.
- It removes the unneeded wasm::GetInstanceMemory function (use
  instance->memory_buffer() directly).
- It moves wasm::GetInstanceMemorySize to
  WasmInstanceObject::GetMemorySize.
- It moves wasm::GrowInstanceMemory to WasmInstanceObject::GrowMemory.
- It moves wasm::GrowWebAssemblyMemory to WasmMemoryObject::Grow.
