Debug Info: Support DW_AT_calling_convention on composite types.
This implements the DWARF 5 feature described at
http://www.dwarfstd.org/ShowIssue.php?issue=141215.1
This allows a consumer to understand whether a composite data type is
trivially copyable and thus should be passed by value instead of by
reference. The canonical example is being able to distinguish the
following two types:
// S is not trivially copyable because of the explicit destructor.
struct S {
~S() {}
};
// T is a POD type.
struct T {
~T() = default;
};
