Fixed a case where the result of std::string's c_str() method was being called on a local variable and returned as a const char * incorrectly. We used to cache the thread names for threads in the current host process, but we shoudn't be caching that as the names can change over time, so now a std::string is returned from Host::GetThreadName().

The FastISEL should be fast. But when we record statistics we use atomic operations to increment the counters.
This patch disables the counters on non-debug builds. This reduces the runtime of SelectionDAGISel::SelectCodeCommon by ~5%.

Test case is missing due to it not being reachable through the current tools
but out of tree code such as the sample at

Consider this case:

  int *p = 0;
  p = getPointerThatMayBeNull();
  *p = 1;

If we inline 'getPointerThatMayBeNull', we might know that the value of 'p'
is NULL, and thus emit a null pointer dereference report. However, we
usually want to suppress such warnings as error paths, and we do so by using
FindLastStoreBRVisitor to see where the NULL came from. In this case, though,
because 'p' was NULL both before and after the assignment, the visitor
would decide that the "last store" was the initialization, not the
re-assignment.

This commit changes FindLastStoreBRVisitor to consider all PostStore nodes
that assign to this region. This still won't catches changes made directly
by checkers if they re-assign the same value, but it does handle the common
case in user-written code and will trigger ReturnVisitor's suppression
machinery as expected.

This enables constructor inlining for types with non-trivial destructors.
The plan is to enable destructor inlining within the next month, but that
needs further verification.

single translation unit should prevent later phases from executing.  Otherwise,

This properly asks TargetLibraryInfo if a call is available and if it is, it
can be translated into the corresponding LLVM builtin. We don't vectorize sqrt()
yet because I'm not sure about the semantics for negative numbers. The other
intrinsic should be exact equivalents to the libm functions.

To afford hand-written tests access to any auto-generated headers, a
lit.site.cfg is now created for cpp11-migrate's test directory providing a new
config.substition. Tests can refer to %gen_root in the LIT script.

Removed use of --param clang_site_config. Not necessary when running
tests using the build system.

ThreadLister is a Linux-specific class for obtaining the thread IDs of a process from procfs (/proc/<pid>/task/). It will be used by leak checking code.
Also add several syscall wrappers which will be required by the same code that uses ThreadLister, but are not used in ThreadLister itself.

After some discussions, it seems that this is the better path in
the long run. Does not change Chromium style, as there, bin packing
is forbidden by the style guide.

Also fix two minor bugs wrt. formatting:
1. If a call parameter is a function call itself and is split before
   the "." or "->", split before the next parameter.
2. If a call parameter is string literal that has to be split onto
   two lines, split before the next parameter.
