Nice, but this still missed to update the documentation on scalar_extract_exp and
scalar_insert_exp, both are ducumented as "require a 64-bit environment".
We need some corresponding updates in gcc/doc/extend.texi.
The others look good to me excepting for one nit in test cases ...

... s/on 64-bit configurations/with 64-bit instructions (-mpowerpc64)/
This is also applied for the below cases with has_arch_ppc64.
