Fix CodeGenCXX/debug-info.cpp test on Windows

On Windows, it looks like FlagIndirectVariable is being set in Flags for
DIBuilder::createLocalVariable(), giving us an i32 of 8192 instead of 0,
as on Linux.

Fixes breakage from r184367.

CodeGen: Don't set 'PMBuilder.DisableSimplifyLibCalls'

The simplify-libcalls pass has been removed from LLVM.  Thus
'PMBuilder.DisableSimplifyLibCalls' does not exist anymore.
The disabling/enabling of library call simplifications is
done through the TargetLibraryInfo which is already wired
up in Clang.

This patch adds new private headers to the module map. Private
headers may be included from within the module, but not from outside
the module.

Call __cxa_begin_catch before std::terminate() in a noexcept trap.

r174939-40 caused us to do this in the canonical terminate lpad,
but when the EH stack has other cleanups on it we use the
terminate handler block, which wasn't doing this.

Fixes the rest of rdar://11904428 given appropriate stdlib support.

Avoid repeatedly evaluating subexpressions when checking for unsequenced

[checked-arithmetic builtins] Added builtins to enable users to perform checked-arithmetic in c.

This will enable users in security critical applications to perform
