Saleem Abdulrasool 159ccc8f51 MC: introduce ability to restrict recorded relocations
Add support to allow a target specific COFF object writer to restrict the
recorded resolutions in the emitted object files.  This is motivated by the need
in Windows on ARM, where an intermediate relocation needs to be prevented from
being emitted in the object file.
