Subject: [Bug fortran/31067] MINLOC should sometimes be inlined (gas_dyn is sooooo sloooow)

gcc47-pr31067.patch

Patch to optimize a = minloc (b) for rank 1 b into a = minloc (b, dim = 1),
according to the standard the latter function is supposed to return the first
element of the array returned by former function (which should return a rank 1,
 1 element array).  So, by instead initializing the (one element) array with
the scalar we can get it actually inlined.  Doing this during genericization
looked much harder to me.
