Hi!
The r13-2943-g11a113d501ff64 made aarch64.h include
aarch64-option-extensions.def, but that file isn't installed

The following patch should fix that, ok for trunk if it
passes bootstrap/regtest + building plugin against it?

When using SWAR (SIMD in a register) techniques a comparison operation within
such a register can be made by using a combination of shifts, bitwise and and
multiplication. If code using this scheme is vectorized then there is potential
to replace all these operations with a single vector comparison

Dear all,
we obviously forgot to extend the C interoperability check of the
type of function results to CLASS variables and thus did not reject
them. Wrong code could lead to an ICE, see testcase by Gerhard.
