Add writeonly IR attribute
Summary:
This complements the earlier addition of IntrWriteMem and IntrWriteArgMem
LLVM intrinsic properties, see D18291.
Also start using the attribute for memset, memcpy, and memmove intrinsics,
and remove their special-casing in BasicAliasAnalysis.

[CodeGen] Make the code that detects a if a shuffle is really a concatenation of the inputs more general purpose.
We can now handle concatenation of each source multiple times. The previous code just checked for each source to appear once in either order.
This also now handles an entire source vector sized piece having undef indices correctly. We now concat with UNDEF instead of using one of the sources. This is responsible for the test case change.

Remove dead TLI arg of isKnownNonNull and propagate deadness. NFC.
This actually uncovered a surprisingly large chain of ultimately unused
TLI args.
From what I can gather, this argument is a remnant of when
isKnownNonNull would look at the TLI directly.
The current approach seems to be that InferFunctionAttrs runs early in
the pipeline and uses TLI to annotate the TLI-dependent non-null
information as return attributes.
This also removes the dependence of functionattrs on TLI altogether.

Summary:
This represents the adjustment applied to the implicit 'this' parameter

always zero unless multiple inheritance is involved.
This increases the size of DISubprogram by 8 bytes, unfortunately. The
adjustment really is a signed 32-bit integer. If this size increase is
too much, we could probably win it back by splitting out a subclass with
info specific to virtual methods (virtuality, vindex, thisadjustment,
