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.

If the LLVM size of a type doesn't match its stride, or a type's size is dynamic, we can't naively lower index_addr to a GEP of the LLVM pointer. We have to bitcast to i8* and GEP the strided distance in bytes. Fixes <rdar://problem/15609900>.

block share the location of the previous instruction.
Fixes <rdar://problem/15597915> Stepping through code occasionally leaps to surprising source lines

Allow archetype_method to look up a witness from a concrete ProtocolConformance record. This will allow generic specialization to apply to constrained generic functions independent of archetype_method devirtualization. <rdar://problem/14748543>

This lets us share implementation with emitArchetypeMethodValue and easily generalize emitArchetypeMethodValue to work with concrete types.

get rid of the hack that used to be in IRGenDebugInfo.
This commit also adds a bunch of interesting testcases for function args.
Fixes <rdar://problem/15464454> Arguments sometimes go missing.

a FuncDecl. This makes it much more straight-forward for SIL passes to
introduce a new one - without doing name lookup in the builtin module!
Swift SVN r10694
Handle an indirect cast from a class existential, so we can cast class existentials to opaque archetype types. Fixes <rdar://problem/15313840>.

Like GlobalAddrInst, but for SILGlobalVariables. These would become the same instruction when SILGlobalVariable can replace AST-level global references.

Instead of hardcoding Builtin.Word to be an alias for Builtin.Int64, make it its own type of abstract pointer width.
- Change BuiltinIntegerType's width representation to accommodate abstract widths.
- In the AST and in SIL, store values of the types as the greatest supported size for the abstract width (64 bits for a pointer).
- Add some type safety to the ([sz]ext|trunc)(OrBitCast)? builtins that they're used appropriately given the upper and lower bounds of the abstract sizes they're working with.
- Now that Builtin.Word is a distinct type, give it its own mangling.
- In IRGen, lower pointer-sized BuiltinIntegerType appropriately for the target, and truncate lowered SIL values if necessary.

(the same way alloc_box returns two) instead of returning a tuple.
This eliminates a ton of tuple_extract instructions, which just
bloat the generated SIL. This resolves rdar://15378135.

GenProto, and emit both the mangled name and the type variable used by the
programmer for archetypes.
Fixes <rdar://problem/15346134> The $swift.type metadata arguments do not show up anymore

Introduces a new flag in SILLocation: InPrologue to mark instructions
that setup the stack and allocate storage for local variables/arguments.
Fixes rdar://problem/15290023: Breakpoint set on prologue - crash ensues.

Use objc_getProtocol to derive a reference to the Protocol* for each required conformance, then pass the array off to a to-be-written dynamicCastObjCProtocol(Un)?Conditional entry point that will do all of the conformsToProtocol checks.
