Hi,

this is yet another obvious patch which I intend to commit in 24h, 
barring objections. In many places in the frontend we were creating a 
tree gfc_c_int_type_node to represent a C int. This is unnecessary, 
since the middle-end already defines such a tree, integer_type_node, 
which fwiw was already used in some places in gfortran.
