[llvm] [AMDGPU] Remove dead D16ImageDimIntrinsic and lookupD16ImageDimIntrinsic (NFC) (PR #221660)

[Kazu Hirata via llvm-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/221660

The corresponding TableGen table and callers were removed on June 21,
2018 in commit 7a9c03f484fee744b1cbcc45e77f949b4ebfcbee, leaving behind
the struct, the declaration, and the unused macro definition.
