introduce a common superclass, SILNode.
This is in preparation for allowing instructions to have multiple
results. It is also a somewhat more elegant representation for
instructions that have zero results. Instructions that are known
to have exactly one result inherit from a class, SingleValueInstruction,
that subclasses both ValueBase and SILInstruction. Some care must be
taken when working with SILNode pointers and testing for equality;
please see the comment on SILNode for more information.
A number of SIL passes needed to be updated in order to handle this
new distinction between SIL values and SIL instructions.
Note that the SIL parser is now stricter about not trying to assign
a result value from an instruction (like 'return' or 'strong_retain')
that does not produce any.
As part of this, re-arrange the argument order so that
generic arguments come before the context, which comes
before the error result. Be more consistent about always
adding a context parameter on thick functions, even
when it's unused. Pull out the witness-method Self
argument so that it appears last after the error
argument.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

This is more in line with all other modules currently on our system.
If/when we get our final name for the language, we're at least now set
up to rename the library without /too/ much trouble. (This is mostly just
a lot of searching for "import swift", "swift.", "'swift'", and '"swift"'.
The compiler itself is pretty much just using STDLIB_NAME consistently now,
per r13758.)

Now that SILFunctionTypes are decontextualized, we have a prayer of parsing SIL that uses generic functions. Fix up the parsing code for ApplyInst and PartialApplyInst so that it consumes the closing '>' after a substitution list and properly computes the substituted function type before resolving the types of the instruction operands.

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.

library. We use the same (somewhat broken heuristics), they are
just implemented in another way.
The major functionality change is that previously, .sil files would
auto import "swift" if they started with a non-sil decl. Now they
never do.

- Allow forward references.
- Diagnose redefinitions.
- Diagnose cases where the use/def of a value mismatch type.
While I'm at it, this fixes a bug where tuple parsing wasn't parsing
the separating commas.
