Extension of D112504. Lower amdgpu printf to `__llvm_omp_vprintf`

passes the size of the void* alloca which will be needed by a non-stub

When processing the devious NAMELIST input

needs to do some look-ahead on the input stream to make sure
that the last "t" on the first line is a truth value rather than
an item name -- which in this case it is. This look-ahead
was implemented in a previous patch but only worked for internal
