[PPC64LE] Implement little-endian semantics for vec_mul[eo]
The PowerPC vector-multiply-even and vector-multiply-odd instructions
are defined architecturally with a big-endian bias, in that the vector
element numbering is assumed to be "left to right" regardless of
whether the processor is in big-endian or little-endian mode. This
definition is unnatural for little-endian code generation.
To facilitate ease of porting, the vec_mule and vec_mulo interfacs are
designed to use natural element ordering, so that elements are
numbered according to little-endian design principles when code is
generated for a little-endian target. The desired semantics can be
achieved by using the opposite instruction for little-endian mode.
That is, when a call to vec_mule appears in the code, a
vector-multiply-odd is generated, and when a call to vec_mulo appears
in the code, a vector-multiply-even is generated.
The correctness of this code is tested by the new mult-even-odd.c test
added in a previous patch. I plan to later make the existing ppc32
Altivec compile-time tests work for ppc64 and ppc64le as well.

This patch fixes a couple of lowering issues for little endian
PowerPC. The code for lowering BUILD_VECTOR contains a number of

those optimizations for correctness. In the future, we will add
analogous optimizations that are correct for little endian.

Fixed several correctness issues in SeparateConstOffsetFromGEP
Most issues are on mishandling s/zext.
Fixes:
1. When rebuilding new indices, s/zext should be distributed to
sub-expressions. e.g., sext(a +nsw (b +nsw 5)) = sext(a) + sext(b) + 5 but not
sext(a + b) + 5. This also affects the logic of recursively looking for a
constant offset, we need to include s/zext into the context of the searching.
2. Function find should return the bitwidth of the constant offset instead of
always sign-extending it to i64.
3. Stop shortcutting zext'ed GEP indices. LLVM conceptually sign-extends GEP
indices to pointer-size before computing the address. Therefore, gep base,
zext(a + b) != gep base, a + b
Improvements:
1. Add an optimization for splitting sext(a + b): if a + b is proven
non-negative (e.g., used as an index of an inbound GEP) and one of a, b is
non-negative, sext(a + b) = sext(a) + sext(b)
2. Function Distributable checks whether both sext and zext can be distributed
to operands of a binary operator. This helps us split zext(sext(a + b)) to
zext(sext(a) + zext(sext(b)) when a + b does not signed or unsigned overflow.
Refactoring:
Merge some common logic of handling add/sub/or in find.

[PPC64LE] Correct vperm -> shuffle transform for little endian
As discussed in cfe commit r210279, the correct little-endian
semantics for the vec_perm Altivec interfaces are implemented by
reversing the order of the input vectors and complementing the permute
control vector. This converts the desired permute from little endian
element order into the big endian element order that the underlying
PowerPC vperm instruction uses. This is represented with a
ppc_altivec_vperm intrinsic function.
The instruction combining pass contains code to convert a
ppc_altivec_vperm intrinsic into a vector shuffle operation when the
intrinsic has a permute control vector (mask) that is a constant.
However, the vector shuffle operation assumes that vector elements are
in natural order for their endianness, so for little endian code we
will get the wrong result with the existing transformation.
This patch reverses the semantic change to vec_perm that was performed
in altivec.h by once again swapping the input operands and
complementing the permute control vector, returning the element
ordering to little endian.
The correctness of this code is tested by the new perm.c test added in
a previous patch, and by other tests in the test suite that fail
without this patch.

[PPC64LE] Implement little-endian semantics for vec_perm
The PowerPC vperm (vector permute) instruction is defined
architecturally with a big-endian bias, in that the two input vectors
are assumed to be concatenated "left to right" and the elements of the
combined input vector are assumed to be numbered from "left to right"
(i.e., with element 0 referencing the high-order element). This
definition is unnatural for little-endian code generation.
To facilitate ease of porting, the vec_perm interface is designed to
use natural element ordering, so that elements are numbered according
to little-endian design principles when code is generated for a
little-endian target. The desired semantics can be achieved with the
vperm instruction provided that the two input vector registers are
reversed, and the permute control vector is complemented. The
complementing is performed using an xor with a vector containing all
one bits.
Only the rightmost 5 bits of each element of the permute control
vector are relevant, so it would be possible to complement the vector
with respect to a <16xi8> vector containing all 31s. However, when
the permute control vector is not a constant, using 255 instead has
the advantage that the vec_xor can be recognized during code
generation as a vnor instruction. (Power8 introduces a vnand
instruction which could alternatively be generated.)
The correctness of this code is tested by the new perm.c test added in
a previous patch. I plan to later make the existing ppc32 Altivec
compile-time tests work for ppc64 and ppc64le as well.

[PECOFF] Support COMDAT associative sections.
COFF supports a feature similar to ELF's section groups. This
patch implements it.
In ELF, section groups are identified by their names, and they are
treated somewhat differently from regular symbols. In COFF, the
feature is realized in a more straightforward way. A section can
have an annotation saying "if Nth section is linked, link this
section too."
Implementing such feature is easy. We can add a reference from a
target atom to an original atom, so that if the target is linked,
the original atom is also linked. If not linked, both will be
dead-stripped. So they are treated as a group.
I added a new reference type, kindAssociate. It does nothing except
preventing referenced atoms from being dead-stripped.
No change to the Resolver is needed.

PR19388: DebugInfo: Emit dead arguments in their originally declared order.
Unused arguments were not being added to the argument list, but instead
treated as arbitrary scope variables. This meant they weren't carefully
added in the original argument order.
In this particular example, though, it turns out the argument is only
/mostly/ unused (well, actually it's entirely used, but in a specific
way). It's a struct that, due to ABI reasons, is decomposed into chunks
(exactly one chunk, since it has one member) and then passed. Since only
one of those chunks is used (SROA, etc, kill the original reconstitution
code) we don't have a location to describe the whole variable.
In this particular case, since the struct consists of just the one int,
once we have partial location information, this should have a location
that describes the entire variable (since the piece is the entirety of
the object).
And at some point we'll need to describe the location of even /entirely/
unused arguments so that they can at least be printed on function entry.
