[Bug c/35442] New: [4.1/4.2/4.3/4.4 regression] Completely broken diagnostic with view_convert_expr

[reichelt at gcc dot gnu dot org]

A broken diagnostic is issued for the following invalid code snippet
since GCC 4.0.2:

==================================================
typedef char A __attribute__((vector_size(8)));
typedef int  B __attribute__((vector_size(8)));

void foo(A a)
{
  ((B)a)();
}
==================================================

#'view_convert_expr' not supported by pp_c_expression#'bugD3.c: In function
'foo':
bug.c:6: error: called object  is not a function
bug.c:5: warning: MMX vector argument without MMX enabled changes the ABI

Similar to PR35441.
