6af5876f72 PerformanceInliner: add the @_semantics("optimize.sil.inline.aggressive") attribute to enable inlining into large functions. 
This attribute overrides the limit of maximum number of basic blocks in the caller.

863f3a19ff Rename @effects to @_effects 
@effects is too low a level, and not meant for general usage outside
the standard library. Therefore it deserves to be underscored like
other such attributes.

c272d41e2f Re-apply "SIL: Remove special meaning for @_semantics("stdlib_binary_only")" 
With -sil-serialize-all gone, this no longer means anything; just
don't declare the function as @_inlineable instead.

Fixes <rdar://problem/34564380>.

9ce3df106e Add two new array semantics functions. 
array.append_element(newElement: Element)
array.append_contentsOf(contentsOf newElements: S)

And allow early inlining of them.
Those functions will be needed to optimize Array.append(contentsOf)

01155076fa [stdlib] [docs] Modify Array's type parameter name and rename Slice to ArraySlice in comments. 
In swift 1.2, `Slice` has been renamed  `ArraySlice`.
In swift 2.0, type parameter name of `Array` is changed from `T` to `Element`.
Therefore, modified the names which appear in code comments and a document.

926042ff81 Add @semantics("optimize.never") to disable optimizations of a specific function. 
This commit adds a flag to disable optimizations on a specific functions. The
primary motivation of this patch is to allow the optimizer developers to reduce
testcasese by disabling optimizations of parts of the code without having to
recompile the compiler or inspect SIL. The annotations  "inline(never)"
and "optimize.none" can go a long way.

The second motivation for this patch is to allow our internal adopters to work
around compiler bugs.

Usage:

@semantics("optimize.never")
public func miscompile() { ... }

404ce8c599 ArraySemantics: Add support for the upcoming array.props semantic calls 
"array.props.isCocoa/needsElementTypeCheck" semantic calls will mark calls that
return array properties: isCocoa and needsElementTypeCheck. We know that said
states can only transfer in certain directions (a native swift array that does
not need an element type check stays in this state) enabling us to version loops
based on the state of said array array properties.
