The current implementation of dealloc_stack in IR-gen is a
no-op, but that's very much wrong for types with non-trivial
local allocation requirements, e.g. archetypes. So we need
to be able to do non-trivial code here. However, that means
modeling both the buffer pointer and the allocated address
in SIL.
To make this more type-safe, introduce a SIL-specific
'[local_storage] T' type that represents the required
allocation for locally storing a T. alloc_stack now returns
one of those in additon to a *T, and dealloc_stack expects
the former.
IR-gen still implements dealloc_stack as a no-op, but
that's now easy to fix.

In SILParser, factor out lookupTopDecl and lookupMember.
lookupTopDecl finds the top-level ValueDecl or Module given a name and
lookupMember finds the ValueDecl given a type and a member name.
Update comments for parseSILDeclRef to match SIL.rst.
We now handle the case where the first component of a dotted path is a
module.
In SILPrinter, print the full path for builtin_function_ref, also
"!" is optional when printing SILDeclRef.

Have project_existential return $*This instead of $Builtin.OpaquePointer, and have protocol_method do the same for methods of opaque protocols. This makes it easier for passes to reason about the semantics of the projected address, since it's restricted by the semantics of SIL addresses.

In parseSILDeclRef, when searching for the first component of the
fully-qualified name, we use UnqualifiedLookup to look through the imports.
Before this commit, only the current module is searched.
Testing cases are generated from a simple swift program using NSObject.

Added types when printing these args in the SIL printer.
As a side effect, I've removed the assertions that check
that we have the correct number of arguments in the Branch instruction
creation routines. The reason is that we do not have a complete block when
parsing and creating the branch instruction and it is possible to add
arguments to a basic block after creation. The assertion will be checked
by the SIL verifier.

Modules can be in either 'Raw' or 'Canonical' form, with different invariants on each. We don't actually distinguish those invariants yet, but this patch adds the field to SILModule and adds a "sil_stage" declaration to SIL printer/parser syntax.

We haven't fully updated references to union cases, and enums still are not
their own thing yet, but "oneof" is gone. Long live "union"!

This way we don't need to deal with the inaccuracy of decimal float literals. While we're here, modify the in-memory representation of IntegerLiteralInst and FloatLiteralInst to save the word array of the APInt instead of round-tripping through plain text.

"SILConstant" doesn't really describe its role in SIL anymore, which is to provide a reference to a Swift declaration in a SIL instruction, such as a method or nominal type field.

- Add the attribute to AnyFunctionType::ExtInfo.
- Propagate the attributes from DeclAttributes to AnyFunctionType for
FuncDecls in TypeCheckDecl.cpp.
- Make sure the new attribute is serialized.
The main missing pieces are checking the applicability of the type attributes
on the FuncDecl and teaching typechecker about conversions on types with
noreturn.

The testing case has a global variable defined in .sil: "var x: Int = 0".
When parsing the .sil file, there was an assertion failure where the type of
ValueDecl for x is null. To fix the problem, we set DelayCheckingPattern to
false for SIL in visitPatternBindingDecl.

-Refactor Parser to stop creating types
-Refactor TypeChecker to create types by resolving TypeReprs.
-Remove "validation" bit from the type system.
We don't need to "validate" every type that gets created but there's still a validation bit in TypeLoc,
necessary because of generic substitutions.
Swift SVN r6326
Modify SILPrinter to print necessary types for parsing.
Format of copy_addr is changed from
copy_addr Src [take]? to Dst [initialization]?
to
copy_addr [take]? Src to [initialization]? Dst : DstType
to put the attribute in front of the actual value.
It also makes parsing easier since '[' can start an array type.
