From-SVN: r233549
This patch adds proper support for the -mtune=z13 option by adding a
z13 pipeline description. As started with zEC12 we mostly make use of
the sched reorder hooks to implement a grouping strategy. However,
this time we also keep an eye at the instruction mix provided in the
out of order window to allow the hardware to exploit the different
units.
