6a6623c596 Do not include DataTypes.h in llvm-c/lto.h.
This means avoid using uint32_t. This patch reverts r112200 and fixes original  problem by fixing argument type in lto.cpp.

Instead of calculating this with mixed types promote all to the
larger type. This enables scalar evolution to analyze this
expression. PR8866

5e8b833707 Add ARM patterns to match EXTRACT_SUBVECTOR nodes.
Also fix an off-by-one in SelectionDAGBuilder that was preventing shuffle
vectors from being translated to EXTRACT_SUBVECTOR.
Patch by Tim Northover.

The test changes are needed to keep those spill-q tests from testing aligned
spills and restores.  If the only aligned stack objects are spill slots, we
no longer realign the stack frame.  Prior to this patch, an EXTRACT_SUBVECTOR
was legalized by loading from the stack, which created an aligned frame index.
Now, however, there is nothing except the spill slot in the stack frame, so
I added an aligned alloca.

6736e19f4c Change EXTRACT_SUBVECTOR to require a constant index.
We were never generating any of these nodes with variable indices, and there
was one legalizer function asserting on a non-constant index.  If we ever have
a need to support variable indices, we can add this back again.

461f1fc359 Use movups to lower memcpy and memset even if it's not fast (like corei7).
The theory is it's still faster than a pair of movq / a quad of movl. This
will probably hurt older chips like P4 but should run faster on current
and future Intel processors. rdar://8817010

8cd4efb6a5 implement constant folding support for an exotic constant expr:
ret i64 ptrtoint (i8* getelementptr ([1000 x i8]* @X, i64 1, i64 sub (i64 0, i64 ptrtoint ([1000 x i8]* @X to i64))) to i64)

to "ret i64 1000".  This allows us to correctly compute the trip count
on a loop in PR8883, which occurs with std::fill on a char array.  This
allows us to transform it into a memset with a constant size.
