Stefan Liebler df3eb8de31 S390: Unify 31/64bit memcpy.
The implementation of memcpy/mempcpy for s390-32 (31bit)
and s390-64 (64bit) is nearly the same.
This patch unifies it for maintability reasons.

__mem[p]cpy_z10 and __mem[p]cpy_z196 differs between 31 and 64bit:
-31bit needs .machinemode "zarch_nohighgprs" and llgfr   %r4,%r4
-lr vs lgr; lgr can be also used on 31bit as this ifunc variant
is only called if we are on a zarch machine.

__mem[p]cpy_default differs between 31 and 64bit:
-Some 31bit vs 64bit instructions (e.g. ltr vs ltgr.
Solved with 31/64 specific instruction macros).
-The address of mvc instruction is setup in different ways
(larl vs bras). Solved with #if defined __s390x__.

__memcpy_mvcle differs between 31 and 64bit:
-lr vs lgr; ahi vs aghi;
Solved with 31/64bit specific instruction macros.

Otherwise 31/64bit implementation has the same structure of the code.
