for halting the propagation of uninitialized value tracking along
a path.  Unlike __attribute__((noreturn)), this attribute (which
is used by clients of the static analyzer) can be used to annotate
functions that essentially never return, but in rare cares may be
allowed to return for (special) debugging purposes.  This attribute
has been shown in reducing false positives in the static analyzer
by pruning false postives, and is equally applicable here.

Handling this attribute in the CFG itself is another option, but
this is not something all clients (e.g., possibly -Wunreachable-code)
would want to see.

Addresses <rdar://problem/12281583>.

The input program may contain intructions which are not inside lifetime
markers. This can happen due to a bug in the compiler or due to a bug in
user code (for example, returning a reference to a local variable).
This commit adds checks that all of the instructions in the function and
invalidates lifetime ranges which do not contain all of the instructions.

'Inputs' subdirectory.

The general desire has been to have essentially all of the non-test
input files live in such directories, with some exceptions for obvious
and common patterns like 'foo.c' using 'foo.h'.

This came up because our distributed test runner couldn't find some of
the headers, for example with stl.cpp.

No functionality changed, just shuffling around here.

information from the Objective-C runtime.

This patch takes the old AppleObjCSymbolVendor and
replaces it with an AppleObjCTypeVendor, which is
much more lightweight.  Specifically, the SymbolVendor
needs to pretend that there is a backing symbol file
for the Types it vends, whereas a TypeVendor only
vends bare ClangASTTypes.  These ClangASTTypes only
need to exist in an ASTContext.

The ClangASTSource now falls back to the runtime's
TypeVendor (if one exists) if the debug information
doesn't find a complete type for a particular
Objective-C interface.  The runtime's TypeVendor
maintains an ASTContext full of types it knows about,
and re-uses the ISA-based type query information used
by the ValueObjects.

Currently, the runtime's TypeVendor doesn't provide
useful answers because we haven't yet implemented a
way to iterate across all ISAs contained in the target
process's runtime.  That's the next step.

While PR13724 is still an issue, it's not actually an issue in the STL.
We can keep this option around in case there turn out to be widespread
false positives due to poor modeling of the C++ standard library functions,
but for now we'd like to get more data.

analysis registers a command, it becomes a "known" command for the lexer, since
it has an ID.  Having this freedom of choice to register a command is a good
thing since BriefParser does not need this.

But the parser should still invoke the correct semantic analysis method
(actOnUnknownCommand) in this case.

reinterpret_cast does not provide any of the usual type information that
static_cast or dynamic_cast provide -- only the new type. This can get us
in a situation where the dynamic type info for an object is actually a
superclass of the static type, which does not match what CodeGen does at all.
In these cases, just fall back to the static type as the best possible type
for devirtualization.

Should fix the crashes on our internal buildbot.
