commit fd5c1f9497 (2014) emits %r_disp32 for pc_rel entries in
.gcc_except_table and .eh_frame, but the specifier is only recognized in
instruction operands, so llvm-mc cannot reassemble llc output.
Implement parseDataExpr with a data specifier table holding just
%r_disp32, and reject %r_disp32 outside a .word directive and in
instruction operands.
Supersedes #208933.
