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.

As part of the final cleanup of aarch64_internal_mov_immediate a return was
accidentally removed. This causes the 2-instruction case to fallthrough
into the general case even when it found a match. An example immediate is
0xcccccccccccccccd which was using 2 instructions in GCC5 but now requires 4.
Adding the return fixes the regressions.
