LLVM/Clang doesn't know the VSX registers when compiling with
-mabi=elfv1. Use only registers >= 32 and list them with their Altivec
name.

The non-signalling versions of VSX scalar convert to shorter/longer
precision insns doesn't silence SNaNs in the hardware. To better match
this behavior, use the non-arithmatic conversion of helper_todouble
instead of float32_to_float64. A test is added to prevent future
regressions.
