A number of optimised memset routines assume the cacheline size is 128B,
so we better check before using them.

We'd like to support processors without Altivec or VSX, so check
the relevant hwcap bits before selecting them.

LGTM.

LGTM.
The patch is still missing the changes for bzero(), but I understand this is
already an improvement over what we had.
I plan to modify bzero later.

The old code had wrong indentation.
Fixed.
LGTM. Pushed as 60b4dd25790342b40e8942e3a4115f511a6b6911.

The code looks good to me, but it's missing the same tests for bzero().
It's also important to keep sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c
in sync with both functions.
Like what this patch does:

A number of optimised memset routines assume the cacheline size is 128B,
so we better check before using them.
