[Bug c/35592] New: Want attribute to enable precision loss warning

["felix-gcc at fefe dot de" <gcc-bugzilla at gcc dot gnu dot org>]

gcc has a warning if one assigns a pointer to an integer of lower width.
I would like to have a way to be warned if someone calls malloc(long long) on
32-bit platforms.  A general warning about integer truncation would generate
lots of spam, so I suggest adding a way to say "if an integer given to this
function is implicitly truncated, that's a bug).  The main target would be
malloc and malloc-like functions, obviously.
