Do not leak SSANAMES in lto streamer
* lto-streamer-in.c (input_cfg): Do not init ssa operands.
(input_function): Do not init tree_ssa and set in_ssa_p.
(input_ssa_names): Do it here.
* tree-ssa.c (init_tree_ssa): Add additional SIZE parameter, default
to 0
* tree-ssanames.c (init_ssanames): Do not round size up to 50, allocate
precisely.
* tree-ssa.h (init_tree_ssa): Update prototype.
