This ensures that we won't try to do cleanups of test cases that we are skipping
e.g. this brings down the time required to run the cmdline category on my machine from ~70s to ~30s

This is a basic implementation - we still don't have any support (that I
know of) for dumping DWARF expressions in a meaningful way, so the
location information itself is just printed as a sequence of bytes as we
do elsewhere.

The compiler occasionally generates multiple .loc directives in a row
(at the same instruction address). These need to be transformed into
multple actual .debug_line table entries, since they are used to signal
certain information to the debugger (e.g. if the opening brace of a
function body is on the same line as the declaration).
The MCAsmStreamer version of EmitDwarfLocDirective handles this
correctly by emitting a .loc directive every time it is called.
However, the MCObjectStream version simply defaults to recording
the information and emitting only a single table entry later,
e.g. when EmitInstruction is called.
This patch introduces a MCAsmStreamer::EmitDwarfLocDirective
version that emits a line table entry for a .loc directive
that may already be pending before recording the new directive.
(This is similar to how this is handled in GNU as.)
With this patch (and the code alignment factor patch) applied,
I'm now getting identical DWARF .debug sections for all test-suite
object files on PowerPC for the internal and the external assembler.

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.

This matches GNU ar behavior. Also remove the now unused getFileStatus method.
Not sure how to add a test, it would have to run ls -l or something like that.

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

sys::fs::make_absolute was turning '.' into '<path>/.' which broke prefix
comparison logic. Stripping these extra chars fixes the problem.

The type <3 x i8> is a common in graphics and we want to be able to vectorize it.
This changes accelerates bullet by 12% and 471_omnetpp by 5%.
