sdesmalen added a parent revision: D81459: [SveEmitter] Add SVE tuple types and builtins for svundef..

The AAPCS specifies that the tuple types such as `svint32x2_t`
should use their `arm_sve.h` names when mangled instead of their
builtin names.

      

This patch also renames the internal types for the tuples to
be prefixed with `__clang_`, so they are not misinterpreted as
specified internal types like the non-tuple types which *are* defined
in the AAPCS. Using a builtin type for the tuples is a purely
a choice of the Clang implementation.
