Subject: [PATCH] [libclc] Delete wrong implementation nvptx clc_isinf

The file calls __nv_isinf which return 1 for true on vector input, while
the generic clc_isinf which return -1 for true on vector input.
Using nvptx clc_isinf in OpenCL isinf violates OpenCL spec.

Found the issue in https://github.com/intel/llvm/pull/22413
