Delete the ARM sub-directory of the SIM directory.
the arm simulator was removed from the sim/ directory. GDB has now
been updated to remove its support for the arm simulator, and as a
result, this header file is no longer used by anyone. Lets delete it.
There should be no user visible changes after this commit.
