opcodes, elf: annotate instructions with HWCAP2_VIS3B.

Browse Source 
This patch annotates the following SPARC instructions as VIS3B
instructions: ldx *, %efsr, fpadd64, fpsub64, fpcmpule8, fpcmpune8,
fpcmpugt8, fpcmpueq8.  It also improves the documentation of the VIS3B
capability in several headers.

Tested in sparc64-unknown-linux-gnu and sparc-unknown-linux-gnu.
No visible regressions.
