Textual SIL was sometimes ambiguous when SILDeclRefs were used, because the textual representation of SILDeclRefs was the same for functions that have the same name, but different signatures.
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.

Verify that witness_method instructions with a lookup type that is an
opened archetype have the optional operand that represents the
open_existential instruction.
I ran into this working supporting substitution of existential types in
mandatory inlining (rdar://problem/17769717).
Swift SVN r23665
Add PrintForSIL in PrintOptions
1> for NameAliasType, we print getSinglyDesugaredType()
I attempted another option: set FullyQualifiedTypes of PrintOptions, but that
will print xxx.Type.xxx and Parser can’t handle it.
2> for Self, we print @sil_self
We also work around parsing:
sil_witness_table _CocoaArrayType: _CocoaArrayType
sil_vtable uses internal classes in stdlib, so we use lookupTopDecl instead
of lookupValue when parsing sil_vtable, to find internal classes.

This only tackles the protocol case (<rdar://problem/17510790>); it
does not yet generalize to an arbitrary "class" requirement on either
existentials or generics.
