rdar://12329730 (2nd part, revised)

The type of shirt-right (logical or arithemetic) should remain unchanged 
when transforming  "X << C1 >> C2" into "X << (C1-C2)"

docs: Fix dead link.

Apparently Dinkumware are no longer hosting their nice reference
manuals. Thankfully, `cppreference.com` can fill that role well.

Add 'using' declarations to suppress -Woverloaded-virtual warnings.

Add a 'getCount' method to get the number of elements in the subrange.

[asan] add experimental -asan-realign-stack option (true by default, which does not change the current behavior)

Add the last part that is needed for vectorization of if-converted code.
Added the code that actually performs the if-conversion during vectorization.

We can now vectorize this code:

for (int i=0; i<n; ++i) {
  unsigned k = 0;

  if (a[i] > b[i])   <------ IF inside the loop.
    k = k * 5 + 3;

  a[i] = k;          <---- K is a phi node that becomes vector-select.
}

Add a 'count' field to the DWARF subrange.

The count field is necessary because there isn't a difference between the 'lo'
and 'hi' attributes for a one-element array and a zero-element array. When the
count is '0', we know that this is a zero-element array. When it's >=1, then
it's a normal constant sized array. When it's -1, then the array is unbounded.

Add a comment about the requirement that the Windows.h header be last.
This comment has the dual effect of blocking reorderings with the
sort_include script.

Address review comments from Matt on the sort_includes.py script.

1) Teach it to handle files with #include on the first line -- these do
   actually exist in LLVM.
2) Support llvm-c and clang-c include projects.
3) Nuke some stail imports.
4) Switch to using os.path to split the file extension off.
5) Remove debugging leftovers.
6) Add docstring (a really puny one) for the sort function.

I'm continuing te avoid stripping the whitespace on the RHS to preserve
whatever newline characters happen to be in the original file.

Give scalar if-converted blocks half the score because they are not always executed due to CF.

Sort includes for all of the .h files under the 'lib' tree. These were
missed in the first pass because the script didn't yet handle include
guards.

Note that the script is now able to handle all of these headers without
manual edits. =]

VMCoreTests/PassManagerTest.cpp: Appease msvc not to do "using llvm::Pass" in class template.

FIXME: I have not checked whether to be compiled on msvc11.

Teach the include sorting script about the gtest headers; sort them with
the system headers.

Teach the include sorter to skip files under test trees and under INPUTS
trees. This allows running the input sorter on the entire clang
repository cleanly now.

Teach the include sorter to quickly skip files with an extension that
doesn't look like it will have C++ code in it.

Suggestions on a better heuristic are welcome.

Sort the #include lines of the examples/... tree.
