Move dwarf2_frame_state_reg.exp_len to union .loc
dwarf2_frame_state_reg.exp_len is only used together with .loc.exp, so
it makes more sense to exp_len to the union as well.
gdb:
2017-08-11 Yao Qi <yao.qi@linaro.org>
* dwarf2-frame.h (struct dwarf2_frame_state_reg) <exp_len>: Remove.
<loc.exp>: New field.
* dwarf2-frame.c (execute_cfa_program): Update.
(dwarf2_frame_prev_register): Update.
