[clang] [clang][CIR] Add tests for SVE NOR intrinsics (PR #233172)

[Vicky Nguyen via cfe-commits]

https://github.com/iamvickynguyen created https://github.com/llvm/llvm-project/pull/233172

Tests for plain SVE `svnor` (https://developer.arm.com/architectures/instruction-sets/intrinsics/#q=svnor).

Port: `clang/test/CodeGen/AArch64/sve-intrinsics/acle_sve_nor.c` to `clang/test/CodeGen/AArch64/sve/nor.c`

Part of https://github.com/llvm/llvm-project/issues/223963.
