- purge @inout from comments in the compiler except for places talking about
the SIL argument convention.
- change diagnostics to not refer to @inout
- Change the astprinter to print InoutType without the @, so it doesn't show
up in diagnostics or in closure argument types in code completion.
- Implement type parsing support for the new inout syntax (before we just
handled patterns).
- Switch the last couple of uses in the stdlib (in types) to inout.
- Various testcase updates (more to come).

Edge SILFunction one step closer to independence from SILFunctionType context by taking the generic param list as a separate constructor parameter, and serializing those params alongside the function record. For now we still pass in the context params from the SILFunctionType in most cases, because the logic for finding the generic params tends to be entangled in type lowering, but this pushes the problem up a step.
Thanks Jordan for helping work out the serialization changes needed.
Compared to r13036, this version of the patch includes the decls_block RecordKind enumerators for the GENERIC_PARAM_LIST layouts in the sil_block RecordKind enumerator, as Jordan had suggested before. r13036 caused buildbot failures when building for iOS, but I am unable to reproduce those failures locally now.

Have SILGen mark all variables bound from pattern bindings without initializers (and *only* ones without initializers) with mark_uninitialized [var] pseudo instructions. On the DI end, *only* consider mark_uninitialized instructions for DI analysis. This has many benefits:
- DI doesn't waste time analyzing locals that are trivially initialized in the original source code.
- DI doesn't try to mangle canonical SIL that has been inlined from transparent functions, which may have been optimized into a form DI isn't written to understand.
While we're here, fix an issue with DCE where it would try to kill unused MarkUninitialized instructions. Although MarkUninitialized has no side effects, it still is semantically important to raw SIL, and can't be killed.
Chris did most of the work here; I just finished updating tests and fixing bugs.

NFC in these cases, just switching to the new APIs, which are only used in situations where they are invariant with the old APIs, except for some function type processing that needs to handle both cases until we can kill off the old APIs.
Swift SVN r12624
Lower types for SILDeclRefs from the interface types of their referents, dragging the old type along for the ride so we can still offer the context to clients that haven't been weaned off of it. Make SILFunctionType's interface types and generic signature independent arguments of its Derive the context types of SILFunctionType from the interface types, instead of the other way around. Do a bunch of annoying inseparable work in the AST and IRGen to accommodate the switchover.
Swift SVN r12536
In general, this forces SILGen and IRGen code that's grabbing
a declaration to state whether it's doing so to define it.
Change SIL serialization to serialize the linkage of functions
and global variables, which means also serializing declarations.
Change the deserializer to use this stored linkage, even when
only deserializing a declaration, and to call a callback to
inform the client that it has deserialized a new entity.
Take advantage of that callback in the linking pass to alter
the deserialized linkage as appropriate for the fact that we
imported the declaration. This computation should really take
advantage of the relationship between modules, but currently
it does not.

Split 'destructive_switch_enum_addr' into separate 'switch_enum_addr' and 'take_enum_data_addr' instructions. This should unblock some optimization work we would like to do with enums.
Swift SVN r12015
Emphasize the fact that this address is only intended for initialization. When we split destructive_switch_enum_addr, there will be another similar instruction for destructively taking the payload out of an already-initialized enum.

Remove the initialize_var instruction now that DI fully diagnoses initialization problems. Change String-to-NSString bridging to explicitly invoke String's default constructor; it was the last remaining user of initialize_var. Remove dead code to emit an implicit default constructor without a body.

- Enhance SILBuilder::emitStrongRelease to be smarter.
- Start using emitStrongRelease in type lowering, SILGen,
CapturePromotion (replacing its implementation of the
same logic), and MandatoryInlining (one more place)
- Rename the primitive createStrongRetain/ReleaseInst
instructions to lose their suffix.
- Now that createStrongRetain/ReleaseInst are not special
cases from the naming perspective, remove some special cases
from DeserializeSIL and ParseSIL.
Swift SVN r10449
- Introduce emitTupleExtract / emitStructExtract, which fold when their operand is a tuple/struct.
- Rename SILBuilder::createTupleExtractInst -> createTupleExtract, "Inst" isn't used as a suffix.
- Switch capture promotion and DI to use the new functions.
This trims 300 lines out of the stdlib.

minor typographical/style changes and use of simpler/strength
reduced apis (e.g. empty() instead of size() != 0).
Stephen, I added a couple of TODOs for simple ways that the
algorithm could be made better, and added a few FIXMEs for
higher priority things that should be taken care of. The
biggest issue is that we need to find a better datastructure
for the reachability queries.
