8f93e159ed ARM64: add i64 scalar pattern for @llvm.arm64.abs
This will be used by the Clang front-end code for vabsd_s64.

e7c7ba0782 [mips] Implement missing relocations in the integrated assembler.
%got_hi, %got_lo, %call_hi, %call_lo, %higher, and %highest are now recognised
by MipsAsmParser::getVariantKind().

To prevent future issues with missing entries in this StringSwitch, I've added
an assertion to the default case.

5900e1db41 [mips] Added a full set of instruction test cases for all ISA's (but not ASE's).
Summary:
Where those ISA's are not currently supported, the test is run with the smallest
superset of that ISA.

Some instructions are valid but don't pass yet. These have been placed in the
valid-xfail.s's which will XPASS if _any_ instruction starts working.

The valid.s's do not verify the encoding yet. There are also no tests checking that instructions from neighbouring ISA's are not accepted.

65fafbb109 Look at shuffles of build_vectors in DAGCombiner::visitEXTRACT_VECTOR_ELT
When the loop vectorizer vectorizes code that uses the loop induction variable,
we often end up with IR like this:

  %b1 = insertelement <2 x i32> undef, i32 %v, i32 0
  %b2 = shufflevector <2 x i32> %b1, <2 x i32> undef, <2 x i32> zeroinitializer
  %i = add <2 x i32> %b2, <i32 2, i32 3>

If the add in this example is not legal (as is the case on PPC with VSX), it
will be scalarized, and we'll end up with a number of extract_vector_elt nodes
with the vector shuffle as the input operand, and that vector shuffle is fed by
one or more build_vector nodes. By the time that vector operations are
expanded, visitEXTRACT_VECTOR_ELT will not create new extract_vector_elt by
looking through the vector shuffle (to make sure that no illegal operations are
created), and so the extract_vector_elt -> vector shuffle -> build_vector is
never simplified to an operand of the build vector.

By looking at build_vectors through a shuffle we fix this particular situation,
preventing a vector from being built, only to be deconstructed again (for the
scalarized add) -- an expensive proposition when this all needs to be done via
the stack. We probably want a more comprehensive fix here where we look back
recursively through any shuffles to any build_vectors or scalar_to_vectors,
etc. but that can come later.

cb1800772a [X86] Adjust cost of FP_TO_UINT v8f32->v8i32
There is no direct AVX instruction to convert to unsigned.  I have some ideas
how we may be able to do this with three vector instructions but the current
backend just bails on this to get it scalarized.

See the comment why we need to adjust the cost returned by BasicTTI.

The test is a bit roundabout (and checks assembly rather than bit code) because
I'd like it to work even if at some point we could vectorize this conversion.

111bcf9b59 Make use of previously generated stores in SelectionDAGLegalize::ExpandExtractFromVectorThroughStack
When expanding EXTRACT_VECTOR_ELT and EXTRACT_SUBVECTOR using
SelectionDAGLegalize::ExpandExtractFromVectorThroughStack, we store the entire
vector and then load the piece we want. This is fine in isolation, but
generating a new store (and corresponding stack slot) for each extraction ends
up producing code of poor quality. When we scalarize a vector operation (using
SelectionDAG::UnrollVectorOp for example) we generate one EXTRACT_VECTOR_ELT
for each element in the vector. This used to generate one stored copy of the
vector for each element in the vector. Now we search the uses of the vector for
a suitable store before generating a new one, which results in much more
efficient scalarization code.

ee8e48d4c9 [PowerPC] Handle VSX v2i64 SIGN_EXTEND_INREG
sitofp from v2i32 to v2f64 ends up generating a SIGN_EXTEND_INREG v2i64 node
(and similarly for v2i16 and v2i8). Even though there are no sign-extension (or
algebraic shifts) for v2i64 types, we can handle v2i32 sign extensions by
converting two and from v2i64. The small trick necessary here is to shift the
i32 elements into the right lanes before the i32 -> f64 step. This is because
of the big Endian nature of the system, we need the i32 portion in the high
word of the i64 elements.

For v2i16 and v2i8 we can do the same, but we first use the default Altivec
shift-based expansion from v2i16 or v2i8 to v2i32 (by casting to v4i32) and
then apply the above procedure.

6da21c0e33 Don't mark the declarations of the TSan annotation functions as weak.
That causes references to them to be weak references which can collapse
to null if no definition is provided. We call these functions
unconditionally, so a definition *must* be provided. Make the
definitions provided in the .cpp file weak by re-declaring them as weak
just prior to defining them. This should keep compilers which cannot
attach the weak attribute to the definition happy while actually
resolving the symbols correctly during the link.

You might ask yourself upon reading this commit log: how did *any* of
this work before? Well, fun story. It turns out we have some code in
Support (BumpPtrAllocator) which both uses virtual dispatch and has
out-of-line vtables used by that virtual dispatch. If you move the
virtual dispatch into its header in *just* the right way, the optimizer
gets to devirtualize, and remove all references to the vtable. Then the
sad part: the references to this one vtable were the only strong symbol
uses in the support library for llvm-tblgen AFAICT. At least, after
doing something just like this, these symbols stopped getting their weak
definition and random calls to them would segfault instead.

Yay software.

4a9804a938 Support: normalize the default triple on Unix
This will fix cross-compiling buildbots (e.g. cygwin).  This is in the same vein
as SVN r205070.  Apply this to fix the cross-compiling scenario, even though the
preferred solution is to update the build system to normalize the embedded
triple rather than perform this at runtime every time.  This is meant to tide us
over until that approach is fleshed out and applied.

190e0a1d63 Detemplatize LOHDirective.
The ARM64 backend uses it only as a container to keep an MCLOHType and
Arguments around so give it its own little copy. The other functionality
isn't used and we had a crazy method specialization hack in place to
keep it working. Unfortunately that was incompatible with MSVC.

Also range-ify a couple of loops while at it.
