with qualifiers on it, we have two distinct types:
- LValueType(T) aka @lvalue T, which is used for mutable values on the LHS of an
assignment in the typechecker.
- InOutType(T) aka @inout T, which is used for @inout arguments, and the implicit
@inout self argument of mutable methods on value types. This type is also used
at the SIL level for address types.
While I detangled a number of cases that were checking for LValueType (without checking
qualifiers) and only meant @inout or @lvalue, there is more to be done here. Notably,
getRValueType() still strips @inout, which is totally and unbearably wrong.

emit the cleanup for the initializing expression when the expression was
complete, instead of at the end of the let decl scope (releasing things
too early).
This fixes rdar://15689514, thanks to DaveA for the great testcase.

of having to lower to an RValue.
This is valuable because we can often emit an expression to a
desired abstraction level more efficiently than just emitting
it to minimal abstraction and then generalizing.

If a struct has [unowned] fields and an implicit elementwise constructor, then the constructor receives a strong reference argument corresponding to the unowned field, and we have to introduce that conversion as part of the construction.
Swift SVN r8207
Tuple exploding happens during RValue construction, so changed the constructor and addElement() method to take the location parameter. The imploding happens on RValue::forwardAsSingleValue and RValue::getAsSingleValue(). Make sure the right SIL locations are passed to all of these
Also, added some missing locations in pattern matching code.
