Previously we determine wave_size of merged shader stages separately, and ignore the condition which may cause them to be different. Now we determine the wave_size of the TCS/GS part first, then use the wave_size for VS/TES part. So that we can condider the previous shader stage's information when determine the wave_size of TCS/GS, and two stages in the merged shader can affect each other's wave_size. This requires si_shader_selector to have two kinds of main part for wave32 and wave64 when part mode, to be combined with other shader part with various wave size. This also enables merged shader stages with different si_shader_info->has_divergent_loop to use wave32. We'll add another condition for KHR_shader_subgroup latter.
