[PATCH] PPC64: Addition of SIMD cosf function for POWER8.

- Reply-to: GT <tnggil at protonmail dot com>
This is the single-precision analogue of the cos function
which we have been discussing the past few weeks.
There should not be much different from the patch implementing
the double-precision version.
A namespace correction for constants in the double-precision
implementation is here. cos/cosf are together in BZ #24205, so it
should be okay that changes for both are in the same patch.
As an aside, while examining the x86_64 implementation, I found
about two-dozen files missing the FSF copyright header. They are
all the single-line files shown when you run this command:

Subject: [PATCH] PPC64: Addition of SIMD cosf function for POWER8.
[BZ #24205]
Implements single-precision cosine using VSX vector capability. The polynomial
cosine-approximating algorithm is adapted for PPC64 from x86_64 [commit #04f496d602].
The patch has been tested on PPC64/POWER8 Little Endian and Big Endian. It is
tested using the framework created for libmvec on x86_64 which runs tests on
issuing 'make check'. Tests of the new vector cosine function all pass.
Details on the ABI are found at this link:
<https://sourceware.org/glibc/wiki/
libmvec?action=AttachFile&do=view&target=VectorABI.txt>
But for adjusting the width of numbers, details described for the
double-precision cosine implemented earlier apply here. See git
commit #4fa62fa562 for that information.

GCC support for auto-vectorization of functions on PPC64 is not yet

inaccessible to applications.

Library libmvec is built by default for PPC64. Disable its creation by
passing flag --disable-mathvec to configure.
