This can cause differences in which bit patterns end up meaning YES or NO. In general, however, 0 == NO and 1 == YES.
To keep it simple, LLDB will now show "YES" and "NO" only for 1 and 0 respectively, and format other values as the plain numeric value instead.

The current code for processCIE and processFDE returns out if it sees
any references. The problem with this is that some references could be
explicit in the binary, while others are implicit as they can be
inferred from the content of the EHFrame itself.
This change walks the references we have against the references we
need, and verifies that all explicit references are in the correct place,
and generates any missing implicit ones.

r263299 added a fixit for the -Wformat-security warning, but that runs
into complications with our guideline that error recovery should be done
as-if the fixit had been applied. Putting the fixit on a note avoids that.

This change adds a header to the printout of the statistics which includes the
time, machine name, and processor info if available. This change also includes
some cosmetic changes like using enum casting for timer and counter iteration.

In the cross-DSO CFI mode clang emits __cfi_check_fail that handles
errors triggered from other modules with targets in the current
module. With this change, __cfi_check_fail will handle errors for
CFI kinds that are not enabled in the current module as if they
have the trapping behaviour (-fsanitize-trap=...).
This fixes a bug where some combinations of -fsanitize* flags may
result in a link failure due to a missing sanitizer runtime library
for the diagnostic calls in __cfi_check_fail.

Annoyingly, ErrorOr allows to *not check* the error when things go
well. It will crash badly when there is an error though. It should
runtime assert when it is used without being checked!

LLVM r263566 adds a generic PACKAGE_VENDOR configuration which can be used to specify the vendor for LLVM toolchain tools. This change defaults the CLANG_VENDOR to the PACKAGE_VENDOR so that you don't have to specify both when building a package.

The builtin library isn't added by the driver unless it exists, so we shouldn't check for it. I've marked this as a FIXME, because we probably should have a way to test this.

This was a latent bug that got exposed by the change to add LoopSimplify
as a dependence to LoopLoadElimination. Since LoopInfo was corrupted
after LV, LoopSimplify mis-compiled nbench in the test-suite (more
details in the PR).
The problem was that when we create the blocks for predicated stores we
didn't add those to any loops.
The original testcase for store predication provides coverage for this
assuming we verify LI on the way out of LV.
Fixes PR26952.

Commit f49839299a085505eb673544744b61d2d9cdd1db in glibc-2.14 changed the
locales to the currently required format. However, they were again changed in
commit 55bdd2866f23b28422d969060b3518909a12b100 which has been released in 2.17.
That leads to the current situation where Debian and e.g. CentOS 6 have the
pre-2.14 locales, for example Ubuntu 14.04 has pre-2.17 and CentOS 7 on the
other hand has the newest locales in glibc-2.17.

On OS X 10.11+, we have "automatic interceptors", so we don't need to use DYLD_INSERT_LIBRARIES when launching instrumented programs. However, non-instrumented programs that load TSan late (e.g. via dlopen) are currently broken, as TSan will still try to initialize, but the program will crash/hang at random places (because the interceptors don't work). This patch adds an explicit check that interceptors are working, and if not, it aborts and prints out an error message suggesting to explicitly use DYLD_INSERT_LIBRARIES.
