Detailed Description
Data formatter for libc++'s std::slice_array.
A slice_array is created by using: operator[](std::slice slicearr); and std::slice is created by: slice(std::size_t start, std::size_t size, std::size_t stride); The std::slice_array has the following members:
- __vp_ points to std::valarray::__begin_ + start
- __size_ is size
- __stride_is stride

This function is assumed to always succeed and if it fails, the front-end should know to deal with it in the correct way (most probably, by refusing to return any children).
The return value of Update should actually be interpreted as "ValueObjectSyntheticFilter cache is good/bad". If this function returns lldb::ChildCacheState::eReuse, ValueObjectSyntheticFilter is allowed to use the children it fetched previously and cached. Otherwise, ValueObjectSyntheticFilter must throw away its cache, and query again for children.
