Adds blacklist parsing behaviour for filtering results into four categories:

 - Expected Protected: Things that are not in the blacklist and are protected.
 - Unexpected Protected: Things that are in the blacklist and are protected.
 - Expected Unprotected: Things that are in the blacklist and are unprotected.
 - Unexpected Unprotected: Things that are not in the blacklist and are unprotected.

Summary:
Stop using the Linux solution with pthread_key_create(3).
This approach does not work on NetBSD, because calling
the thread destructor is not the latest operation on a POSIX
thread entity. NetBSD's libpthread still calls at least
pthread_mutex_lock and pthread_mutex_unlock.

Detect _lwp_exit(2) call as it is really the latest operation
called from a detaching POSIX thread.

This resolves one set of crashes observed in
the Thread Sanitizer execution.

This recommit r317351 after fixing a buildbot failure.

Original commit message:

    Summary:
    This change add a pass which tries to split a call-site to pass
    more constrained arguments if its argument is predicated in the control flow
    so that we can expose better context to the later passes (e.g, inliner, jump
    threading, or IPA-CP based function cloning, etc.).
    As of now we support two cases :

    1) If a call site is dominated by an OR condition and if any of its arguments
    are predicated on this OR condition, try to split the condition with more
    constrained arguments. For example, in the code below, we try to split the
    call site since we can predicate the argument (ptr) based on the OR condition.

    Split from :
          if (!ptr || c)
            callee(ptr);
    to :
          if (!ptr)
            callee(null ptr)  // set the known constant value
          else if (c)
            callee(nonnull ptr)  // set non-null attribute in the argument

    2) We can also split a call-site based on constant incoming values of a PHI
    For example,
    from :
          BB0:
           %c = icmp eq i32 %i1, %i2
           br i1 %c, label %BB2, label %BB1
          BB1:
           br label %BB2
          BB2:
           %p = phi i32 [ 0, %BB0 ], [ 1, %BB1 ]
           call void @bar(i32 %p)
    to
          BB0:
           %c = icmp eq i32 %i1, %i2
           br i1 %c, label %BB2-split0, label %BB1
          BB1:
           br label %BB2-split1
          BB2-split0:
           call void @bar(i32 0)
           br label %BB2
          BB2-split1:
           call void @bar(i32 1)
           br label %BB2
          BB2:
           %p = phi i32 [ 0, %BB2-split0 ], [ 1, %BB2-split1 ]

[X86] Promote athlon, athlon-xp, k8, and k8-sse3 to types instead of subtypes in getHostCPUName. NFCI

This removes the athlon type and simplifies the string decoding. We only really need these type/subtype breaks where we need to match libgcc/compiler-rt and these CPUs aren't part of that.

I'm looking into moving some of this information to a .def file to share with clang's __builtin_cpu_is handling. And while these CPUs aren't part of that the less lines I have to deal with in the .def file the better.

Reland "Add support for writing 64-bit symbol tables for archives when offsets become too large for 32-bit"

Tests were failing because some bots were running out of address
space and memory. Additionally the test was very slow. These issues
were solved by changing the test to take advantage of sparse filse and
restricting the test to run only on 64-bit systems.

This should fix https://bugs.llvm.org//show_bug.cgi?id=34189

This change makes it so that if writing a K_GNU style archive, you need
to output a > 32-bit offset it should output in K_GNU64 style instead.

This commit implements the semicolon insertion logic into the extract
refactoring. The following rules are used:

- extracting expression: add terminating ';' to the extracted function.
- extracting statements that don't require terminating ';' (e.g. switch): add
  terminating ';' to the callee.
- extracting statements with ';':  move (if possible) the original ';' from the
  callee and add terminating ';'.
- otherwise, add ';' to both places.

Summary:
This change adds Scudo as a possible Sanitizer option via -fsanitize=.
This allows for easier static & shared linking of the Scudo library, it allows
us to enforce PIE (otherwise the security of the allocator is moot), and check
for incompatible Sanitizers combo.

In its current form, Scudo is not compatible with any other Sanitizer, but the
plan is to make it work in conjunction with UBsan (-fsanitize=scudo,undefined),
which will require additional work outside of the scope of this change.
