47c919a8 - [clang][Driver] Ensure intermediate bitcode files are written according to `/Fo` (#189977)

[clang][Driver] Ensure intermediate bitcode files are written according to `/Fo` (#189977) With the following compilation process: ``` $ mkdir -p src/ tmp/ $ cat << 'EOF' > src/main.c int main() { return 0; } EOF $ clang-cl /c /Fo:tmp/ /clang:-fembed-bitcode src/main.c ``` the object file `main.obj` is generated in the `tmp/` directory but the intermediate `main.bc` is placed in the current working directory. This PR ensures that intermediate `.bc` files are written to the same directory specified by `/Fo`.
