for getting the name of the module file, unifying the code for
searching for a module with a given name (into lookupModule()) and
separating out the mapping to a module file (into
getModuleFileName()). No functionality change.

invalid -fvisibility=protected, but that information doesn't seem
to exist at the most appropriate time, so I've left a FIXME behind.

as method will not consume the argument when receiver is null.

There is really no reason to have these only available on x86. It's
just __builtin_c[tl]z for shorts.

single attribute ("system") that allows us to mark a module as being a
"system" module. Each of the headers that makes up a system module is
considered to be a system header, so that we (for example) suppress
warnings there.
If a module is being inferred for a framework, and that framework
directory is within a system frameworks directory, infer it as a
system framework.

We can now use "-Wno-everything -W<warning>" to ignore all warnings except
specific ones.

the direct serialization of the linked-list structure. Instead, use a
scheme similar to how we handle redeclarations, with redeclaration
lists on the side. This addresses several issues:
- In cases involving mixing and matching of many categories across
many modules, the linked-list structure would not be consistent
across different modules, and categories would get lost.
- If a module is loaded after the class definition and its other
categories have already been loaded, we wouldn't see any categories
in the newly-loaded module.

ARM supports clz and ctz directly and both operations have well-defined
results for zero. There is no disadvantage in performance to using the
defined-at-zero versions of llvm.ctlz/cttz intrinsics. We're running into
ARM-specific code written with the assumption that __builtin_clz(0) == 32,
even though that value is technically undefined. The code is failing now
because of llvm optimizations that are taking advantage of the undef
behavior (specifically svn r147255). There's nothing wrong with that
optimization on x86 where any incorrect assumptions about __builtin_clz(0)
will quickly be exposed. For ARM, though, optimizations based on that undef
behavior are likely to cause subtle bugs. Other targets with defined-at-zero
clz/ctz support may want to override the default behavior as well.

normalization. This used to be captured in DefaultTargetTriple and is
used for the (optional) $triple-$tool lookup for cross-compilation.
Do this properly by making it an attribute of the toolchain and use it
in combination with the computed triple as index for the toolchain
lookup.

At this point this is largely cosmetic, but it opens the door to replace
ProgramStateRef with a smart pointer that more eagerly acts in the role
of reclaiming unused ProgramState objects.

declarator just because we were able to build an invalid decl
for it. The invalid-type diagnostics, in particular, are still useful
to know, and may indicate something about why the decl is invalid.
Also, recover from an illegal pointer/reference-to-unqualified-retainable
type using __strong instead of __autoreleasing; in general, a random
object is much more likely to be __strong, so this avoids unnecessary
cascading errors in the most common case.
