[NFC] Remove LinkAll*.h

But that doesn't make sense, correct WPO will not remove functions we actually use.

I noticed these because compiling cc1_main.cpp was pulling in random LLVM pass headers.

To force the load/linking of your register allocator into the
:program:`llc`/:program:`lli` tools, add your creator function's global
declaration to ``Passes.h`` and add a "pseudo" call line to
