This commit replaces the new_src parameter of nir_ssa_def_rewrite_uses()
with an SSA def, removes nir_ssa_def_rewrite_uses_ssa(), and rewrites
all the users as needed.

When using nir_lower_interpolation, we need to propagate the IO
semantics from the load_interpolated_input to the new
load_fs_input_interp_deltas intrinsics. nir_lower_io assumes
they will be filled out.
This fixes assertions in most tests on iris since commit
01ab308edc, where nir_lower_io
started reading this field.
Fixes: 01ab308edc ("nir: update IO semantics in nir_io_add_const_offset_to_base")
Fixes: 502abfce7f ("nir: save IO semantics in lowered IO intrinsics")
