968f69cf66 Add -enable-experimental-lifetime-dependence-inference option 
Until stdlib can be built with noncopyable generics, stdlib types
can appear as ~Escapable and ~Copyable, leading to invalid inference.

Use a flag to test implicit lifetime dependence

Treat it as a contextual keyword when followed by an identifier, like our
other ownership-related declarations and operators.

0a4c029cfc [AST] Introduce UnreachableExpr 
This models the conversion from an uninhabited
value to any type, and allows us to get rid of

9b64990d24 [AST] Remove the "single expression body" bit 
Remove this bit from function decls and closures.
Instead, for closures, infer it from the presence
of a single return or single expression AST node
in the body, which ought to be equivalent, and
automatically takes result builders into
consideration. We can also completely drop this
query from AbstractFunctionDecl, replacing it
instead with a bit on ReturnStmt.

f4a6b95d24 Move single-expr return transform from Parse to Sema 
Rather than doing the transform in the parser, and
then potentially undoing it in Sema, move the
entire transform into Sema. This also lets us
unify the logic between function decls and
closures, and allows ASTGen to benefit from it.

ad584a7945 [sil] Add getOperand() variants for pack instructions. 
We already had getValue() variants... this just expands those to operands. The
reason why this is useful is that these instructions have specific operands with
specific meanings as assigned by an internal enum struct. Rather than having to
access those directly by using getAllOperand()[EnumCase]... better to have a
named method.

5441ff1d97 [MoveChecker] Distinguished scope end diagnostics. 
There are several kinds of scopes at which it is required that an
address be initialized:
(1) the whole function -- for inout argument to the function
(2) the region a coroutine is active -- for an inout yielded by a
    coroutine into the function
(3) the region of a memory access -- for a `begin_access [modify]`.

The move checker enforces that they are initialized at that point by
adding instructions at which the field must be live to liveness.

Previously, all such scopes used the end of the function as the point at
which the memory had to have been reinitialized.  Here, the relevant end
of scope markers are used instead.

More importantly, here the diagnostic is made to vary--the diagnostic,
that is, that is issued in the face an address not being initialized at
the end of these different kind of scopes.
