[PATCH, rs6000] Fix vector long long subtype (PR96139)
Hi,
This corrects an issue with the powerpc vector long long subtypes.
As reported by SjMunroe, when building some code with -Wall, and
attempting to print an element of a "long long vector" with a
long long printf format string, we will report an error because
the vector sub-type was improperly defined as int.
When defining a V2DI_type_node we use a TARGET_POWERPC64 ternary to
define the V2DI_type_node with "vector long" or "vector long long".
We also need to specify the proper sub-type when we define the type.
Due to some file renames, This is a backport and rework of both
[PATCH, rs6000] Fix vector long long subtype (PR96139)
and
[PATCH, rs6000] Testsuite fixup pr96139 tests
