If we're using emitExprInto to emit a LoadExpr, we can handle that by emitting a copy_addr from the underlying lvalue to the initialization instead of building and storing the rvalue, which plays better with the direction we're taking for value semantics optimizations.
This is currently guarded behind a flag -enable-silgen-lvalue-peepholes because it introduces a miscompile in the stdlib that crashes some tests; requires further investigation before making live.

This is only useful for unique-identification uses of the mangler, like in SourceKit,
which has to deal with invalid code.
Since this is not related to ABI, we can change the encoding anytime we want.

This should allow declarations inside protocols to mangle successfully, which is needed by SourceKit to be able to use mangled names as unique decl identifiers. I'm also planning to use mangled protocol decls to name generic curry thunk symbols.
This only introduces a mangling for independent associated types. I think we will eventually want to mangle dependent associated types (such as T.AssocType for an archetype T : SomeProtocol) with a non-indexed mangling too, but this doesn't do that yet.

k = UncurriedFunctionType
k = UncurriedFunctionMetaType
k = Type
k = MetaType
to:
k = UncurriedFunctionType
k = MetaType
This should help Greg parse uncurried functions with greater ease

The previous implementation of the tree structure for the demangler had a bug in the low-level tree management code which caused the tree structure to diverge depending on whether
nodes were added as siblings or children. This checkin fixes the issue by making sure that the tree of nodes is kept coherent at all times.
Some adjustments are necessary to ensure the nodes were still generated properly and correctly turned into strings
Added a new test case
Swift SVN r7643
Previously, substitutions were treated as unstructured text chunks, but this was causing problems when using the demangler as a source of structured type information
This patch ensures that substitutions are properly stored as the type they represent for later semantic reconstruction
Swift SVN r7494
This commit changes the Swift demangler to produce a tree-like list of tokens instead of a string.
This is mostly useful for LLDB since we can use the inherent structure in a Swift mangled name to make more informed decisions about matters such as type information extraction from modules
The ability to convert the tokenized output into a plain string for viewing purposes is of course preserved

integration
Motivation: libIDE clients should be simple, and they should not have to
translate token-based SourceRanges to character locations.
This also allows us to remove the dependency of DiagnosticConsumer on the
Lexer. Now the DiagnosticEngine translates the diagnostics to CharSourceRanges
and passes character-based ranges to the DiagnosticConsumer.

new definitive initialization work until it is ready to be on by default.
This needs to be a langoption as well, because it will affect some of the
things SILGen does.

Every valid source location corresponds to a source buffer. There should be no
cases where we create a source location for a random string. Thus,
findBufferContainingLoc() always succeeds.
Swift SVN r7120
Added a -v(verbose) option to swift that will trigger verbose printing in SIL
Printer. SIL Printer will print the location info only in the verbose mode.
Here is the example of the format - only the line and colon are displayed for
brevity:
%24 = apply %13(%22) : $[cc(method), thin] ((), [byref] Bool) -> Builtin.Int1 // user: %26 line:46:10
(This will be used to test the validity of SILLocation info.)

Note that the import kind is not checked yet; this is effectively our old
behavior for "import swift.print".
Infrastructure: move Module::forAllVisibleModules out-of-line, and add
makeStackLambda to STLExtras for using a non-escaping lambda with
std::function.
Swift SVN r6852
Also centralizes the knowledge about whether the hashbang is allowed in the
SourceManager. This fixes a bug in tokenize() because previously it just had
to guess.
