Separate out the notions of 'has a trivial special member' and 'has a
non-trivial special member', and use them appropriately. These are not
opposites of one another (there might be no special member, or in C++11 there
might be a trivial one and a non-trivial one). The CXXRecordDecl predicates
continue to produce incorrect results, but do so in fewer cases now, and
they document the cases where they might be wrong.
No functionality changes are intended here (they will come when the predicates
start producing the right answers...).

more sense anyway - it determines how expressions are codegen'd. It also ensures
that -ffp-contract=fast has the intended effect when compiling LLVM IR.

type as written from the ParmVarDecl; it's unclear whether the standard
(C99 6.9.1p10) requires this, but we're following the precedent set by gcc,
and hopefully nobody will ever ask about this again.

If we have a type 'int a[1]' and a type 'int b[0]', the generated DWARF is the
same for both of them because we use the 'upper_bound' attribute. Instead use
the 'count' attrbute, which gives the correct number of elements in the array.

at whether the *selected* constructor would be trivial rather than considering
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.

disabling byval, we set realign to true.
It will perform an aligned alloca, and call memcpy to copy the byval
argument to the local variable.
Change the size threshold back to 64 bytes.

after an #include that triggers a module import, which might use
either Sema or the AST consumer before it would have been initialized.

it also increases the size threshold for turning on byval.
A backend fix will be attempted.

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.
