Explicit declarations and fixed bindings

Use let for fixed bindings, var for reassignment and the optional strict declaration policy to require explicit new names.

// Requires the updated native development runtime for --strict-declarations.
// aner check examples/strict_declarations.aner --strict-declarations
// aner run examples/strict_declarations.aner --strict-declarations
let increment = 2
var total = 10
total += increment

// let fixes the handle, while the array retains its mutable-storage contract.
let samples = Array<Int64>(size: 2, fill: 0)
samples[0] = total
samples[1] = total + increment
print(total)
print(samples[1])
// Expected output:
// 12
// 14
