Michael Matz 25b2779c3d x86-64: Fix stdarg for large non-float structs ...

Some structs are passed in registers.  When they need more than
one the implementation of __va_arg on x86-64 didn't correctly account
for this.  This fixes only the cases where the structs consist of
integer types, as there the register save area is consecutive.

Fixes some tests from 73_arm64.c, but still leaves those failing
that use floating point in the large-but-regpassed structs.
