ARM: Support SingleParameterDotFile on WoA

Currently, the integrated assembler is the only choice for assembling Windows on
ARM binaries.  IAS supports the .file <filename> directive which emits the file
symbol into the resulting object binary.  Mark the GNU COFF information to
indicate support for this feature.
