4a3a46af13 InnoDB: Performance optimizations based on OProfile analysis
innobase/btr/btr0btr.c:
  Eliminate some buf_frame_align() calls.
  Make use of the page_rec_is_infimum(), page_rec_is_supremum()
  and page_rec_is_user_rec() functions.
  Replace some index->table->comp with page_is_comp().
  Eliminate some variables to reduce register spilling on x86.
  Note that page_is_comp() may return nonzero instead of TRUE.
  Note that rec_offs_comp() may return nonzero instead of TRUE.
innobase/btr/btr0cur.c:
  Eliminate some buf_frame_align() calls.
  Replace some index->table->comp with
  page_is_comp() or rec_offs_comp().
  Eliminate some variables to reduce register spilling on x86.
  Note that page_is_comp() may return nonzero instead of TRUE.
  Note that rec_offs_comp() may return nonzero instead of TRUE.
  Remove an extra mem_heap_create() call from btr_cur_update_in_place().
  Add "page" parameter to lock_rec_store_on_page_infimum().
  Add some UNIV_LIKELY() and UNIV_UNLIKELY() hints.
