ef3a611ddb stdlib: make sure that Array._copyBuffer is not inlined. 
Although it’s called via _slowPath the compiler sometimes inlines it, because it considers it to be a trivial function.
This change gives small code size improvements for benchmarks which deal with arrays.

0a448ea74b SE-0138: Minor update. Array.withUnsafeBytes is nonmutating. 
The "mutating" keyword should not have been on this API. The example
code in SE-0138 uses it as a nonmutating API.

(The mutating keyword was a temporary workaround that should never
have been carried over to the swift-3.0-branch).

f70a2e083e SE-0138: Add UnsafeRawBufferPointer and UnsafeMutableRawBufferPointer. (#4954) 
https://github.com/apple/swift-evolution/blob/master/proposals/0138-unsaferawbufferpointer.md

Unsafe[Mutable]RawBufferPointer is a non-owning view over a region of memory as
a Collection of bytes independent of the type of values held in that
memory. Each 8-bit byte in memory is viewed as a `UInt8` value.

Reads and writes on memory via `Unsafe[Mutable]RawBufferPointer` are untyped
operations. Accessing this Collection's bytes does not bind the
underlying memory to `UInt8`. The underlying memory must be bound
to some trivial type whenever it is accessed via a typed operation.

In addition to the `Collection` interface, the following methods from
`Unsafe[Mutable]RawPointer`'s interface to raw memory are
provided with debug mode bounds checks: `load(fromByteOffset:as:)`,
`storeBytes(of:toByteOffset:as:)`, and `copyBytes(from:count:)`.

This is only a view into memory and does not own the memory. Copying a value of
type `UnsafeMutableRawBufferPointer` does not copy the underlying
memory. Assigning an `Unsafe[Mutable]RawBufferPointer` into a value-based
collection, such as `[UInt8]` copies bytes out of memory. Assigning into a
subscript range of UnsafeMutableRawBufferPointer copies into memory.

266a5f90bd stdlib: Use builtin tail-allocated arrays instead of ManagedBuffer to allocate contiguous array buffers. 
This reduces the amount of SIL generated for array operations significantly.
The generated code should be mostly the same (modulo different inlining decisions).
