Speed up jnt_comp search

(1). If 1/2 of model_rd of compound modes are larger than rd of
jnt_comp, choose jnt_comp and stop searching.

(2). In motion_mode_rd, if it's jnt_comp mode, do not search
interintra.

(3). If motion vector is GLOBAL_GLOBALMV, do not search jnt_comp mode.

STATS_CHANGE
Performance: 0.02% worse (because GLOBAL_GLOBALMV is skipped),
on Google test 30 frames lowres

Speed up: not significant, within 3%.
