Remove dead code in switch conv pass.
2019-11-14 Martin Liska <mliska@suse.cz>
* tree-switch-conversion.c (switch_conversion::switch_conversion):
Do not initialize m_other_count.
(switch_conversion::collect): Do not count m_default_count and
m_other_count as we use frequencies for edges.
* tree-switch-conversion.h: Remove m_default_count and m_other_count.
