RFR: 8373255: Unexpected iobj and ipdb files after JDK-8370438

[Erik Joelsson]

When using `-LTCG` with Visual Studio, then by default, the linker will output an extra `.iobj` file in the same directory as the target file. In the OpenJDK build that means this file, along with the accompanying `.ipdb` file, will end up in the JDK image. To fix this, we need to apply a similar fix to JDK-8372643 and add an extra parameter that defines the location of this file.
