Previously we would always write a hash of the binary into the PE file, for reproducible builds. This breaks AppCompat, which is a feature of Windows that relies on the timestamp in the PE header being set to a real value (or at the very least, a value that satisfies certain properties). To address this, we put the old behavior of writing the hash behind the /Brepro flag, which mimics MSVC linker behavior. We also match MSVC default behavior, which is to write an actual timestamp to the PE header. Finally, we add the /TIMESTAMP option (an lld extension) so that the user can specify the exact value to be used in case he/she manually constructs a value which is both reproducible and satisfies AppCompat.
