Use the unique filenames that are used when /lldsavetemps is passed.
After this change, module names for LTO blobs in PDBs will be unique.
Visual Studio and probably other debuggers expect module names to be
unique.
Revert some changes from 1e0b158db (2017) that are no longer necessary
after removing MSVC LTO support.

// If LTO is in use, your input files are not in regular COFF files

// a COFF file that contains native code. This file provides that
