Fix bug 1059738 (make innodb_fake_changes faster -- prefetch sibling
pages).

Fix adapted from lp:mysqlatfacebook/51, revision 3791, with the
difference that the sibling pages are not latched at all.

- Add new btr_latch_mode value BTR_SEARCH_TREE that is similar
  BTR_MODIFY_TREE except that it does not X-latch the sibling pages of
  the given leaf.
- btr_cur_latch_leaves(): handle BTR_SEARCH_TREE by fetching the
  sibling leaf pages by reading them without latching and then
  immediately unfixing them from the buffer.
- row_ins_index_entry_low(), row_upd_clust_rec(): use BTR_SEARCH_TREE
  instead of BTR_MODIFY_TREE in case of fake changes.
