[swift-evolution] [Review] SE-0101: Rename sizeof and related functions to comply with API Guidelines

[Hooman Mehr]

How about we get rid of dynamicType by adding instance level properties as well:

public struct MemoryLayout<T> {
    
    public static var size: Int { return sizeof(T) }
    public static var interval: Int { return strideof(T) }
    public static var alignment: Int { return alignof(T) }
    
    public var size: Int { return sizeof(T) }
    public var interval: Int { return strideof(T) }
    public var alignment: Int { return alignof(T) }
    
    init(_ : @autoclosure () -> T) {}
}

print(MemoryLayout<Int>.size) // 8
print(MemoryLayout<Int>.interval) // 8
print(MemoryLayout<Int>.alignment) // 8

let x = 8

print(MemoryLayout(x).size) // 8
print(MemoryLayout(x).interval) // 8
print(MemoryLayout(x).alignment) // 8
