Summary: LTO backend will not invoke SampleProfileLoader pass even if -fprofile-sample-use is specified. This patch passes the flag down so that pass manager can add the SampleProfileLoader pass correctly.

There is a synchronization point between the reference count of a block dropping to zero and it's destruction, which TSan does not observe. Do not report errors in the compiler-emitted block destroy method and everything called from it.

The checker has several false positives that this patch addresses:
- Do not check if the return status has been compared to error (or no error) at the time when leaks are reported since the status symbol might no longer be alive. Instead, pattern match on the assume and stop tracking allocated symbols on error paths.
- The checker used to report error when an unknown symbol was freed. This could lead to false positives, let's not repot those. This leads to loss of coverage in double frees.
- Do not enforce that we should only call free if we are sure that error was not returned and the pointer is not null. That warning is too noisy and we received several false positive reports about it. (I removed: "Only call free if a valid (non-NULL) buffer was returned")
- Use !isDead instead of isLive in leak reporting. Otherwise, we report leaks for objects we loose track of. This change triggered change #1.

This also adds checker specific dump to the state.

 * Do not initialize these variables when initializing the rest of the
   thread_locals in the TU; they have unordered initialization so they can be
   initialized by themselves.

   This fixes a rejects-valid bug: we would make the per-variable initializer
   function internal, but put it in a comdat keyed off the variable, resulting
   in link errors when the comdat is selected from a different TU (as the per
   TU TLS init function tries to call an init function that does not exist).

 * On Darwin, when we decide that we're not going to emit a thread wrapper
   function at all, demote its linkage to External. Fixes a verifier failure
   on explicit instantiation of a thread_local variable on Darwin.

When a textual header is present inside a umbrella dir but not in the
header, we get the misleading warning:

warning: umbrella header for module 'FooFramework' does not include
header 'Baz_Private.h'

The module map in question:

framework module FooFramework {
    umbrella header "FooUmbrella.h"

    export *
    module * { export * }

    module Private {
        textual header "Baz_Private.h"
    }
}

Fix this by taking textual headers into account.

Summary:
We do not currently track the source locations for exception specifications such
that their source range can be queried through the AST. This leads to trying to
write more complex code to determine the source range for uses like FixItHints
(see D18575 for an example). In addition to use within tools like clang-tidy, I
think this information may become more important to track as exception
specifications become more integrated into the type system.

A hotfix for pr31592 that fixes the crash but not the root cause of the problem.
We need to update the analyzer engine further to account for AST changes
introduced in r289618. At the moment we're erroneously performing a redundant
lvalue-to-rvalue cast in this scenario, and squashing the rvalue of the object
bound to the reference into the reference itself.

Fixes a crash in modules where the template class decl becomes the most recent
decl in the redeclaration chain and forcing the template instantiator try to
instantiate the friend declaration, rather than the template definition.
    
In practice, A::list<int> produces a TemplateSpecializationType

This flag serves no purpose other than to prevent us walking through a type to
check whether it contains an 'auto' specifier; this duplication of information
is error-prone, does not appear to provide any performance benefit, and will
become less practical once we support C++1z deduced class template types and
eventually constrained types from the Concepts TS.

No functionality change intended.

Fix a crash in body farm when synthesizing a getter for a property
synthesized for a property declared in a protocol on a class extension
that shadows a declaration of the property in a category.

In this case, Sema doesn't fill in the implicit 'self' parameter for the getter
in the category, which leads to a crash when trying to synthesize the getter
for it.

To avoid the crash, skip getter synthesis in body farm if the self parameter is
not filled int.
