The ARM cycle-counter can be restricted by the operating system; it's
worth warning potential users of this issue.

 - There is no reason to have a modules specific flag for disabling
   autolinking. Instead, convert the existing flag into -fno-autolink (which
   should cover other autolinking code generation paths like #pragmas if and
   when we support them).

This turns on not only destructor inlining, but inlining of constructors
for types with non-trivial destructors. Per r178516, we will still not
inline the constructor or destructor of anything that looks like a
container unless the analyzer-config option 'c++-container-inlining' is
set to 'true'.

In addition to the more precise path-sensitive model, this allows us to
catch simple smart pointer issues:

  #include <memory>

  void test() {
    std::auto_ptr<int> releaser(new int[4]);
  } // memory allocated with 'new[]' should not be deleted with 'delete'

For variables and functions clang used to store two storage classes. The one
"as written" in the code and a patched one, which, for example, propagates
static to the following decls.

This apparently is from the days clang lacked linkage computation. It is now
redundant and this patch removes it.
