Fix a nasty bug in DAGCombine of STORE nodes.
This is very related to the bug fixed in r174431. The problem is that
SelectionDAG does not include alignment in the uniquing of loads and
stores. When an otherwise no-op DAGCombine would increase the alignment
of a load or store, the original node would be returned (with the
alignment increased), which would cause the node not to be processed by
any further DAGCombines.

target, but I did see some noise in the tests for other targets and have
updated them for it.

[InstCombine] Don't fold a GEP into itself through a PHI node
This can only occur (I think) through the back-edge of the loop.
However, folding a GEP into itself means that the value of the previous
iteration needs to be stored in the meantime, thus requiring an
additional register variable to be live, but not actually achieving
anything (the gep still needs to be executed once per loop iteration).
The attached test case is derived from:
typedef unsigned uint32;
typedef unsigned char uint8;
inline uint8 *f(uint32 value, uint8 *target) {
while (value >= 0x80) {
value >>= 7;
++target;
}
++target;
return target;
}
uint8 *g(uint32 b, uint8 *target) {
target = f(b, f(42, target));
return target;
}
What happens is that the GEP stored in incptr2 is folded into itself
through the loop's back-edge and the phi-node stored in loopptr,
effectively incrementing the ptr by "2" in each iteration instead of "1".
In this case, it is actually increasing the number of GEPs required as
the GEP before the loop can't be folded away anymore. For comparison:
With this patch:

check-llvm-codegen-arm - Runs the ARM codeine tests

CMake: Disable ENABLE_EXPORTS for executables with MSVC
The MSVC linker won't produce a .lib file for an executable that doesn't
export anything, and LLVM doesn't maintain dllexport annotations or .def
files listing all C++ symbols. It also doesn't support exporting all
symbols, like binutils ld.
CMake 3.2 changed the Ninja generator to list both the .exe and .lib
files as outputs of executable build targets. Ninja would always re-link
executables with ENABLE_EXPORTS because the .lib output file was not
present, and therefore the target was out of date.

Currently v2i64 vectors shifts (non-equal shift amounts) are scalarized, costing 4 x extract, 2 x x86-shifts and 2 x insert instructions - and it gets even more awkward on 32-bit targets.
This patch separately shifts the vector by both shift amounts and then shuffles the partial results back together, costing 2 x shuffles and 2 x sse-shifts instructions (+ 2 movs on pre-AVX hardware).
Note - this patch only improves the SHL / LSHR logical shifts as only these are supported in SSE hardware.

Fix bug while building FP16 constant vectors for AArch64
Summary: Building FP16 constant vectors caused the FP16 data to be bitcast to i64. This patch creates a BITCAST node with the correct value, and adds a test to verify correct handling.

Remove StringRef->std::string->StringRef conversions.
As StringInit::get() accepts StringRef there is no need
to construct a std::string out of the StringRef input and
then construct a new StringRef from the std::string.

DebugInfo: Drop fake DW_TAG_expression
Break MDExpression off of DebugNode (inherit directly from `MDNode`) and
drop the fake `DW_TAG_expression` tag in the process.
AFAICT, there's no real functionality change here. The tag was
originally used by `DIDescriptor::isExpression()` to discriminate
between `MDNode`s, but in the new hierarchy we don't need that.
Fixes PR22780.

Emit the offset directly instead of creating a dummy expression.
We were creating an expression of the form (S+C)-S which is just C.
