* nimRawSetjmp: support Windows Using `_setjmp()` directly is required to avoid some rare (but very annoying) exception-related stack corruption leading to segfaults on Windows, with Mingw-w64 and SEH. More details: https://github.com/status-im/nimbus-eth2/issues/3121 Also add "nimBuiltinSetjmp" - mostly for benchmarking. * fix for Apple's Clang++
