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.

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"!

Add a getBits() method to FloatLiteralInst so we don't need to round trip APInt -> APFloat -> APInt to print the bits in the printer. Use allocateLiteralInstWithBitSize instead of -WithTextSize to avoid wasting space.
Swift SVN r6680
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.
Swift SVN r6559
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.

In the resilience model for default arguments, the presence of a
default argument is API, but its specific value is not. Thus, the
actual default argument values can evolve over time. To implement
this, for each default argument, we emit a function that
takes no arguments and produces the default value for that
argument. The caller will then call that function to form the default
argument.
This commit emits these functions for each default argument, even
though they are not currently being called. This is part of
<rdar://problem/11561185>.
We'll probably want a different calling convention for these functions
that preserves all registers, since they will often end up being very
trivial functions.

Construct ArchetypeType from generic params; Construct a Scope for the SIL
function body so TypeAliasDecl for the generic params can be added to ScopeInfo.
Remove an extra '$' in SILPrinter when printing the lookup type for an
archetype_method.
Swift SVN r6219
These still need to be serialized, because they are one-to-one with the
type's protocol list, but don't actually require any data. Found on
attempting to emit a module for the standard library.
Most of the churn here is moving Interleave.h to a more general STLExtras.h.

New format for SILConstant:
'#' sil-dotted-path sil-constant-kind-and-uncurry-level?
sil-dotted-path:
identifier ('.' identifier)*
sil-constant-kind-and-uncurry-level:
'!' sil-constant-kind ('.' sil-constant-uncurry-level)? ('.objc')?
'!' sil-constant-uncurry-level ('.objc')?
'!objc'
sil-constant-kind:
'func' | 'getter' | 'setter' | 'allocator' | 'initializer' | 'oneofelt' \
| 'destroyer' | 'globalaccessor'
Add helper function printFullContext in SILPrinter to generate the fully
qualified dotted path for a given DeclContext; Add parseSILConstant to
SILParser; Testing cases are updated to reflect the new format.
Swift SVN r6055
Improve our representations of casts in the AST and SIL so that 'as!' and 'is' (and eventually 'as?') can share almost all of the same type-checking, SILGen, and IRGen code.
In the AST, we now represent 'as!' and 'is' as UnconditionalCheckedCastExpr and IsaExpr, respectively, with the semantic variations of cast (downcast, super-to-archetype, archetype-to-concrete, etc.) discriminated by an enum field. This keeps the user-visible syntactic and type behavior differences of the two forms cleanly separated for AST consumers.
At the SIL level, we transpose the representation so that the different cast semantics get their own instructions and the conditional/unconditional cast behavior is indicated by an enum, making it easy for IRGen to discriminate the different code paths for the different semantics. We also add an 'IsNonnull' instruction to cover the conditional-cast-result-to-boolean conversion common to all the forms of 'is'.
The upshot of all this is that 'x is T' now works for all the new archetype and existential cast forms supported by 'as!'.
