Modified the implementation of fs::GetUniqueID on Windows such that it actually finds a unique identifier for a file.  Also adds unit tests for GetUniqueID.

This is the first patch in a series of patches to rename isNormal =>
isFiniteNonZero and isIEEENormal => isNormal. In order to prevent careless
errors on my part the overall plan is:

1. Add the isFiniteNonZero predicate with tests. I can do this in a method
independent of isNormal. (This step is this patch).
2. Convert all references to isNormal with isFiniteNonZero. My plan is to
comment out isNormal locally and continually convert isNormal references =>
isFiniteNonZero until llvm/clang compiles.
3. Remove old isNormal and rename isIEEENormal to isNormal.
4. Look through all of said references from patch 2 and see if we can simplify
them by using the new isNormal.

Prior to this change, the considered addressing modes may be invalid since the
maximum and minimum offsets were not taking into account.
This was causing an assertion failure.

The added test case exercices that behavior.

<rdar://problem/14199725> Assertion failed: (CurScaleCost >= 0 && "Legal
addressing mode has an illegal cost!")

Summary:
A trailing block comment having multiple lines would cause extremely
high penalties if the summary length of its lines is more than the column limit.
Fixed by always considering only the last line of a multi-line block comment.
Removed a long-standing FIXME from relevant tests and added a motivating test
modelled after problem cases from real code.

Corrections to r184205 ('this'-return optimization) due to the wrong version of the patch being committed originally.
1) Removed useless return value of CGCXXABI::EmitConstructorCall and CGCXXABI::EmitVirtualDestructorCall and implementations
2) Corrected last portion of CodeGenCXX/constructor-destructor-return-this to correctly test for non-'this'-return of virtual destructor calls

This is in preparation for the backwards references to bound
nodes, which will expose a lot more about how matches occur.  Main
changes:
- instead of building the tree of bound nodes, we build a "set" of bound
  nodes and explode all possible match combinations while running
  through the matchers; this will allow us to also implement matchers
  that filter down the current set of matches, like "equalsBoundNode"
- take the set of bound nodes at the start of the match into
  consideration when doing memoization; as part of that, reevaluated
  that memoization gives us benefits that are large enough (it still
  does - the effect on common match patterns is up to an order of
  magnitude)
- reset the bound nodes when a node does not match, thus never leaking
  information from partial sub-matcher matches for failing matchers

Effects:
- we can now correctly "explode" combinatorial matches, for example:
  allOf(forEachDescendant(...bind("a")),
  forEachDescendant(...bind("b"))) will now trigger matches for all
  combinations of matching "a" and "b"s.
- we now never expose bound nodes from partial matches in matchers that
  did not match in the end - this fixes a long-standing issue

FIXMEs:
- rename BoundNodesTreeBuilder to BoundNodesBuilder or
  BoundNodesSetBuilder, as we don't build a tree any more; this is out
  of scope for this change, though
- we're seeing some performance regressions (around 10%), but I expect
  some performance tuning will get that back, and it's easily worth
  the increase in expressiveness for now
