Compilation with vcc or clang (msvc) on Windows fails by using nimRawSetjmp

[rockcavera]

This error only happens with clang msvc compiler. In the clang gnu compiler this does not happen. The default LLVM installer for Windows is msvc.

Example

# test.nim
echo "test"

Current Output

@rockcavera Hello, could you try not defined(clang) or clang_cl here => https://github.com/nim-lang/Nim/pull/19899/files

I tried and the error persists.

The problem also happens with the vcc compiler:

[rockcavera]

I fixed the problem with vcc.

The problem with clang can be fixed as well. But the variation between clang msvc or gnu complicates a bit. The clang-cl I'm not sure would be the msvc abi.

[rockcavera]

The biggest problem with clang on Windows is that the default target is msvc in the installer available for download from the llvm website. So much so that for this, to differentiate the msvc and gnu clang, I did it here. You will only use clang-cl if you want some msvc cl option.

#20758

#19891 has been reverted, it shouldn't cause problems by default.
