Fix cmpli usage in power6 memset.
Building glibc for powerpc64 with recent (2.27.51.20161012) binutils,
with multi-arch enabled, I get the error:
../sysdeps/powerpc/powerpc64/power6/memset.S: Assembler messages:
../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: operand out of range (5 is not between 0 and 1)
../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: operand out of range (128 is not between 0 and 31)
../sysdeps/powerpc/powerpc64/power6/memset.S:254: Error: missing operand
Indeed, cmpli is documented as a four-operand instruction, and looking
at nearby code it seems likely cmpldi was intended. This patch fixes
this powerpc64 code accordingly, and makes a corresponding change to
the powerpc32 code.
Tested for powerpc, powerpc64 and powerpc64le by Tulio Magno Quites

* sysdeps/powerpc/powerpc32/power6/memset.S (memset): Use cmplwi
instead of cmpli.
* sysdeps/powerpc/powerpc64/power6/memset.S (memset): Use cmpldi
instead of cmpli.
