Revert r371729: lld-link: Make /linkrepro: take a filename, not a directory.

Browse Source 
This reverts commit r371729 because /linkrepro option also exists
in Microsoft link.exe and their linker takes not a filename but a
directory name as an argument for /linkrepro.

COFF Improvements
-----------------
* /linkrepro: now takes the filename of the tar archive it writes, instead
of the name of a directory that a file called "repro.tar" is created in,
matching the behavior of ELF lld.
* The new `/lldignoreenv` flag makes lld-link ignore environment variables
like `%LIB%`.
* ...
MinGW Improvements
