Richard,
this patch adds folding for the new GOACC_DIM_POS and GOACC_DIM_SIZE
internal
functions.  IIUC gimple_fold_call is the right place to add this.

The size of a compute dimension is very often a compile-time
constant.  On the
host, in particular it's 1, which means we can deduce the POS must be
zero.

ok?
