[clang] [clang] Replace PointerUnion::dyn_cast with llvm::dyn_cast (NFC) (PR #232603)

[Kazu Hirata via cfe-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/232603

PointerUnion::dyn_cast has been soft-deprecated in favor of
llvm::dyn_cast and llvm::dyn_cast_if_present.  This patch replaces the
former with llvm::dyn_cast where the operand is guaranteed to be
nonnull.

Note that Origin::Ptr is always initialized to a nonnull pointer in
OriginManager::createNode and never modified afterward.
