[libc][math] Improve performance test framework (#134501) 2025-04-24T11:22:21+00:00 Tejas Vipin alissxlace@proton.me 2025-04-24T11:22:21+00:00 dde00f5e22e81ac88b37d1502d2383985a58329d - Merges `BinaryOpSingleOutputPerf.h` and `SingleInputSingleOutputPerf.h` files into a unified `PerfTest.h` and update all performance tests to use this. - Improve the output printed to log file for tests. - Removes unused `run_diff` method and redundant `run_perf` call in `BINARY_INPUT_SINGLE_OUTPUT_PERF_EX` (previously `BINARY_OP_SINGLE_OUTPUT_PERF_EX`) - Change `BINARY_INPUT_SINGLE_OUTPUT_PERF_EX` and `SINGLE_INPUT_SINGLE_OUTPUT_PERF` to not define `main` 
- Merges `BinaryOpSingleOutputPerf.h` and
`SingleInputSingleOutputPerf.h` files into a unified `PerfTest.h` and
update all performance tests to use this.
- Improve the output printed to log file for tests.
- Removes unused `run_diff` method and redundant `run_perf` call in
`BINARY_INPUT_SINGLE_OUTPUT_PERF_EX` (previously
`BINARY_OP_SINGLE_OUTPUT_PERF_EX`)
- Change `BINARY_INPUT_SINGLE_OUTPUT_PERF_EX` and
`SINGLE_INPUT_SINGLE_OUTPUT_PERF` to not define `main`
