Let risu accept elf test files, adjusted from v1.
Adjust risugen to invoke the assembler and linker,
with a cross-compiler prefix if needed.
Add some sparc64 testing which utilizes this.
Changes for v2:
- Implement VIS2 through VIS4.
There's something odd going on with the Sparc M8 Solaris host where
the values recorded via RISU for some floating-point operations are
incorrectly rounded, but performing the same operations with the
same inputs in a standalone test program produces correct results.
I wonder if there's some unfinished_FPop exception being generated
and the operating system emulation is producing incorrect results.
I'd be much happier if I could test this on Linux...

Nice! I don't have any experience with RISU so I don't feel too qualified to review
the series, but obviously there are clear benefits to having SPARC support included :)
ATB,
