Remove false positives for warnings that break LTO profiled
* tree.h (tree_vec_elt_check): Workaround -Wstrict-overflow
false positive during profiledbootstrap.
* decl.c (attr_decl1): Workaround -Wmaybe-uninitialized
false positive during profiledbootstrap by initializing them.
* matchexp.c (match_mult_operand): Likewise.
* module.c (write_atom): Likewise.
(read_module): Likewise.
