This reverts commit r28892, r28894, and r28895.
They broke validation tests; JoeG is going to look at what's needed to
make them work again.
Swift SVN r28897
This has passed review, or at least satisfied Tony Parker, provided we
do something to hide SetAlgebraDispatchType. I think I can eliminate it
in an imminent commit.
Swift SVN r28892
Currently they do nothing but allow stdlib code to use regular (Bool)
types. However, soon the wrappers for the _native variants will
provide point-of-use sanity checking.
These need to be fully generic to support class protocols and
single-payload enums (not just for optional). It also avoids a massive
amount of overloading for all the reference type variations
(AnyObject, Native, Unknown, Bridge) x 2 for optional versions of
each.
Because the wrapper is generic, type checking had to be deferred until
IRGen. Generating code for the wrapper itself will result in an
IRGen-time type error. They need to be transparent anyway for proper
diagnostics, but also must be internal.
Note that the similar external API type checks ok because it
forces conformance to AnyObject.
The sanity checks are disabled because our current facilities for
unsafe type casting are incomplete and unsound. SILCombine can
remove UnsafeMutablePointer and RawPointer casts by assuming layout
compatibility. IRGen will later discover layout incompatibility and
generate a trap.
I'll send out a proposal for improving the casting situation so we can
get the sanity checks back.

includes a number of QoI things to help people write the correct code. I will commit
the testcase for it as the next patch.
The bulk of this patch is moving the stdlib, testsuite and validation testsuite to
the new syntax. I moved a few uses of "as" patterns back to as? expressions in the
stdlib as well.

This reverts commit 64e9f11211a19fa603f5bc2d2bea171a9b07d3fa.
I think this is breaking ExistentialCollection test in the
Release + stdlib asserts build.

Fixes <rdar://problem/18151694> Add Builtin.checkUnique to avoid lost Array copies
The isUniquelyReference APIs are now correct in the presence of full
inlining and ARC optimization. The ARC optimizer can't see into the
Builtin, which lowers to a special SIL instruction.
Swift SVN r27929
The rule changes are as follows:
* All functions (introduced with the 'func' keyword) have argument
labels for arguments beyond the first, by default. Methods are no
longer special in this regard.
* The presence of a default argument no longer implies an argument
label.
The actual changes to the parser and printer are fairly simple; the
rest of the noise is updating the standard library, overlays, tests,
etc.
With the standard library, this change is intended to be API neutral:
I've added/removed #'s and _'s as appropriate to keep the user
interface the same. If we want to separately consider using argument
labels for more free functions now that the defaults in the language
have shifted, we can tackle that separately.
