sparc: Assume VIS3 support
This patch assumes VIS3 support by binutils, which is supported since
version 2.22. This leads to some code simplification, mostly on
multiarch build where there is only one variant instead of previously
two (whether binutils supports VIS3 instructions or not).
For multiarch files where HAVE_AS_VIS3_SUPPORT was checked and
the default implementation was built with a different name, a new
file with (implementation with -generic appended) is added.
Checked on sparc64-linux-gnu and sparcv9-linux-gnu.
