HPF adds one new intrinsic function, `ILEN`, which computes the
number of bits needed to store an integer value. HPF also generalizes
the Fortran 90 `MAXLOC` and `MINLOC` intrinsic functions with an
optional `DIM` parameter, for finding the locations of maximum or minimum
elements along a given dimension.
