This patch adds a new set of conformance tests for single-precision math functions provided by the LLVM libm for GPUs. The functions included in this set were selected based on the following criteria: - An implementation exists in `libc/src/math/generic` (i.e., it is not just a wrapper around a compiler built-in). - The corresponding LLVM CPU libm implementation is correctly rounded. - The function is listed in Table 65 of the OpenCL C Specification v3.0.19.
