  [LLVM] Introduce 'llvm-offload-wrapper' tool (#153504)

Summary:
This is a standalone tool that does the wrapper stage of the
`clang-linker-wrapper`. We want this to be an external tool because
currently there's no easy way to split apart what the
clang-linker-wrapper is doing under the hood. With this tool, users can
manually extract files with `clang-offload-packager`, feed them through
`clang --target=<triple>` and then use this tool to generate a `.bc`
file they can give to the linker. The goal here is to make reproducing
the linker wrapper steps easier.

  [clang-tools-extra] Replace SmallSet with SmallPtrSet (NFC) (#154365)

This patch replaces SmallSet<T *, N> with SmallPtrSet<T *, N>.  Note
that SmallSet.h "redirects" SmallSet to SmallPtrSet for pointer
element types:

  template <typename PointeeType, unsigned N>
class SmallSet<PointeeType*, N> : public SmallPtrSet<PointeeType*, N>
{};

We only have 10 instances that rely on this "redirection", with more
than half of them under clang-tools-extra/.  Since the redirection
doesn't improve readability, this patch replaces SmallSet with
SmallPtrSet for pointer element types.

I'm planning to remove the redirection eventually.

  [NVPTXLowerArgs] Add align attribute to return value of addrspace.wrap intrinsic (#153889)

If alignment inference happens after NVPTXLowerArgs these addrspace wrap
intrinsics can prevent computeKnownBits from deriving alignment of
loads/stores from parameters. To solve this, we can insert an alignment
annotation on the generated intrinsic so that computeKnownBits does not
need to traverse through it to find the alignment.

  [RISCV] Handle more cases when combining (vfmv.s.f (extract_subvector X, 0)) (#154175)

Previously, we fold `(vfmv.s.f (extract_subvector X, 0))` into X when
X's type is the same as `vfmv.s.f`'s result type. This patch generalizes
it by folding it into insert_subvector when X is narrower and
extract_subvector when X is wider.
