requires pushing the types out. The only interesting one is this diff:
- var (e,f,g:(),h) = MRV()
+ var (e,f,g,h) : (Int, Float, (), Double) = MRV()
... where the type annotation is required to silence the warning about "void type
may be unexpected". This seems perfectly reasonable to me.

If a non-static 'let' field in a struct has an initializer, its implicitly generated
memberwise initializer should not override that. Handle this by having the memberwise initializer
and default initializer use the initial value of the property instead of an argument to the init.
This would have been a lot easier if sema was synthesizing the ctor bodies instead of SILGen,
but here it is. The missing case is narrow (let (x,y) = (1,2)) and for now we just disable
implicit synthesization of the incorrect case.

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.

Have the ArgumentInitVisitor directly bind argument variables to BB arguments, instead of trying to reuse the InitializationForPattern logic used for general variable bindings. That was a nice idea, but it leads to some ugly edge cases because of the many little ways arguments are different from local variable bindings. By getting rid of the abstraction layers, it's easy for argument binding to bind +0 guaranteed or +1 arguments in place when appropriate, avoiding an r/r pair for "let" bindings. It will also let us eliminate some ugly code from variable binding initialization. Should be NFC aside from some harmless reordering of prolog/epilog variable setup.

Change all the existing addressors to the unsafe variant.
Update the addressor mangling to include the variant.
The addressor and mutable-addressor may be any of the
variants, independent of the choice for the other.
SILGen and code synthesis for the new variants is still
untested.

them in a more consistent and principled way. Two changes here: MUI is generated
when a vardecl is emitted, not as a separate "MarkPatternUninitialized" pass. Second,
when generating a MUI for self parameters with a temporary alloc_stack (due to the
possibility of superclass remapping of self) emit the MUI on the allocation itself,
not on the incoming argument. This is a lot more consistent (dissolving a bunch of
hacks in DI).
In terms of behavior changes, this only changes the raw sil generated by SILGen and
consumed by DI, so there is no user-visible change. This simply unblocks future work.

Now the SILLinkage for functions and global variables is according to the swift visibility (private, internal or public).
In addition, the fact whether a function or global variable is considered as fragile, is kept in a separate flag at SIL level.
Previously the linkage was used for this (e.g. no inlining of less visible functions to more visible functions). But it had no effect,
because everything was public anyway.
For now this isFragile-flag is set for public transparent functions and for everything if a module is compiled with -sil-serialize-all,
i.e. for the stdlib.
For details see <rdar://problem/18201785> Set SILLinkage correctly and better handling of fragile functions.
The benefits of this change are:
*) Enable to eliminate unused private and internal functions
*) It should be possible now to use private in the stdlib
*) The symbol linkage is as one would expect (previously almost all symbols were public).
More details:
Specializations from fragile functions (e.g. from the stdlib) now get linkonce_odr,default
linkage instead of linkonce_odr,hidden, i.e. they have public visibility.
The reason is: if such a function is called from another fragile function (in the same module),
then it has to be visible from a third module, in case the fragile caller is inlined but not
the specialized function.
I had to update lots of test files, because many CHECK-LABEL lines include the linkage, which has changed.
The -sil-serialize-all option is now handled at SILGen and not at the Serializer.
This means that test files in sil format which are compiled with -sil-serialize-all
must have the [fragile] attribute set for all functions and globals.
The -disable-access-control option doesn't help anymore if the accessed module is not compiled
with -sil-serialize-all, because the linker will complain about unresolved symbols.
A final note: I tried to consider all the implications of this change, but it's not a low-risk change.
If you have any comments, please let me know.

The issue here is that SILGen is expecting the argument pattern for the
synthesized ConstructorDecl to line up with the stored property list for the
decl containing the constructor. This is super fragile and probably the wrong
way to go (it would be better for sema to synthesize the entire ctor and make it
not be magical at all in silgen), but do a small fix to improve the situation
by inserting the lazy property storage next to the computed lazy property.
