arch/tile: add Tilera's <arch/sim.h> header as an open-source header
This change adds one of the Tilera standard <arch> headers to the set
of headers shipped with Linux. The <arch/sim.h> header provides
methods for programmatically interacting with the Tilera simulator.
The current <arch/sim.h> provides inline assembly for the _sim_syscall
function, so the declaration and definition previously provided
manually in Linux are no longer needed. We now use the standard
sim_validate_lines_evicted() method from <arch/sim.h> rather than
rolling our own direct call to sim_syscall().
