Conrad Meyer 2a4fd6b17a ioat: Add support for Block Fill operations 
The IOAT hardware supports writing a 64-bit pattern to some destination
buffer.  The same limitations on buffer length apply as for copy
operations.  Throughput is a bit higher (probably because fill does not
have to spend bandwidth reading from a source in memory).

Support for testing Block Fill has been added to ioatcontrol(8) and the
ioat_test device.  ioatcontrol(8) accepts the '-f' flag, which tests
Block Fill.  (If the flag is omitted, the tool tests copy by default.)
The '-V' flag, in conjunction with '-f', verifies that buffers are
filled in the expected pattern.

Tested on:	Broadwell DE (Xeon D-1500)
