Fix some hash_table build errors when configured with
--enable-checking=yes.

tree-browser.c
   * Remove stale declaration of removed TB_parent_eq.
   * Fix template parameter for base class to match value_type.

gimple.h
   * Use gimplify_hasher::hash rather than gimple_tree_hash in the
   assertion check.
   * Change return values to match return type. (I.e. no conversions.)

Tested on x86-64.

Committing to branch as obvious.
