Changes

GPUizing Various Small Routines (#1080)

* GPUizing compute_Cx_fnc_Richardson

* GPUizing term_wp2_splat and term_wp3_splat

* GPUizing xp3_LG_2005_ansatz

* GPUizing calculate_thvm

* GPUizing pvertinterp even though I don't think we care about the l_do_expldiff_rtm_thlm flag

* Fixing bug. Setting l_do_expldiff_rtm_thlm causes us to use edsclrm, so we need to also ensure that edsclrm > 1 (1 because it uses a edsclr_dim-1 index)

* Pushing some data statements up the call tree.
