Attributes @__objc_bridged, @__raw_doc_comment and @__accessibility are not supposed to be
coming from input file and actually crash parseNewDeclAttribute(…) when they are.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

This will let the performance inliner inline a function even if the costs are too high.
This attribute is only a hint to the inliner.
If the inliner has other good reasons not to inline a function,
it will ignore this attribute. For example if it is a recursive function (which is
currently not supported by the inliner).
Note that setting the inline threshold to 0 does disable performance inlining at all and in
this case also the @inline(__always) has no effect.

This disables inlining at the SIL level. LLVM inlining is still enabled. We can
use this to expose one function at the SIL level - which can participate in
dominance based optimizations but which is implemented in terms of a cheap check
and an expensive check (function call) that benefits from LLVM's inlining.
Example:
The inline(late) in the example below prevents inlining of the two checks. We
can now perform dominance based optimizations on isClassOrObjExistential.
Without blocking inlining the optimizations would apply to the sizeof check
only and we would have multiple expensive function calls.
@inline(late)
func isClassOrObjExistential(t: Type) -> Bool{
return sizeof(t) == sizeof(AnyObject) &&
swift_isClassOrObjExistential(t)
}
We do want inlining of this function to happen at the LLVM level because the
first check is constant folded away - IRGen replaces sizeof by constants.

I am trying to enable a new ARC optimizer feature that is forcing me to
debug a test case that is affected by inlining of initializers. Plus, being
able to selectively disable inlining of the initializers is a useful
feature in general.

them to cover all declaration types.
This ensures that we reject attributes on declkinds where they don't make sense. I went so far
as to make the QoI decent when an attribute can only be applied to a single kind of declaration
to make sure the error message says "@IBAction is only valid on 'func' declarations" as well.

This only tackles the protocol case (<rdar://problem/17510790>); it
does not yet generalize to an arbitrary "class" requirement on either
existentials or generics.

When type checking a patternbindingdecl with an initializer, we check the
initializer expression, then apply the inferred type to the pattern. This
works except that we get down to a NamedPattern, see that it has various
attributes on it (e.g. iboutlet, weak) that affect the type of the pattern,
and we weren't re-propaging it back out through the pattern. Do that.
