You removed the include guard - why not keep it?

I changed test_calling_conv implementation changed from C to C++ - so I decided
to add the Subzero_ prefix in the C++ way by using a namespace. This requires
including the test_calling_conv.h header twice in the driver - which the include
guards won't allow.

+#include "test_calling_conv.def"
+#include "vectors.h"
+
+typedef void (*CalleePtrTy)();
+extern CalleePtrTy Callee;
+extern size_t ArgNum;
+extern char *Buf;
+
+void caller_i();
+void caller_alloca_i();
+typedef void callee_i_Ty(int);
+callee_i_Ty callee_i;
+callee_i_Ty callee_alloca_i;
+
+void caller_vvvvv();
+typedef void (callee_vvvvv_Ty)(v4si32, v4si32, v4si32, v4si32, v4si32);
+callee_vvvvv_Ty callee_vvvvv;
+
+void caller_vlvlvfvdviv();
+typedef void(callee_vlvlvfvdviv_Ty)(v4f32, int64_t, v4f32, int64_t, v4f32,
+                                    float, v4f32, double, v4f32, int, v4f32);
+callee_vlvlvfvdviv_Ty callee_vlvlvfvdviv, Subzero_callee_vlvlvfvdviv;
