[llvm] [AArch64] Remove unused references to MVT::f80. (PR #169545)

[David Green via llvm-commits]

https://github.com/davemgreen created https://github.com/llvm/llvm-project/pull/169545

These f80 fp types are only supported on X86 and can be removed from AArch64. It looks like they were copied from another backend by mistake.
