whether the array's element type has *any* non-trivial constructors of the
relevant kind.

This is useful because unnamed bitfields can have effects on the
offsets which are not otherwise reflected in the DWARF information.

it also increases the size threshold for turning on byval.

zero-extended to 64 bits.  This information is currently provided to
the back end by setting "signext" or "zeroext" attributes.  However,
this is done only for integer types *smaller* than i32, not for i32
itself.  This causes clang to generate code violating the ABI, which
results in a failure of the tramp3d-v4 test case (due to calling a
system library routine without ABI-required extension).

This patch implements custom versions of classifyArgumentType and
classifyReturnType for PPC64_SVR4_ABIInfo, which are the same as the
default versions except that they also classify "int" and "unsigned int"
as types needing extending.  This fixed tramp3d-v4 on PowerPC64.

We want the diagnostic, and if the load is optimized away, we still want to
