ef91b93e6d branches/zip: Minor performance tuning based on measurement data
on mispredicted branches: opcontrol --event=BR_CND_MISSP_EXEC:45000

UT_SORT_FUNCTION_BODY(): Copy the array with memcpy(3).

cmp_dtuple_rec_with_match(), cmp_rec_rec_with_match(),
cmp_debug_dtuple_rec_with_match(): Add UNIV_UNLIKELY hints around
tests for REC_INFO_MIN_REC_FLAG.

ec4059555b branches/zip: cmp_rec_rec_simple(): Compare n_uniq columns instead of
all columns present in offsets.  Add a const qualifier to the
dict_index_t* parameter.

1a8a63d0cd branches/zip: Reimplement merge sort in fast index creation.
The creation of the primary key does not work.  We will have to flag
externally stored columns and copy the externally stored part from
the old table.

row_build_index_for_mysql(): Rename to row_merge_build_indexes().
Move from row0mysql.c to row0merge.c.

Remove private declarations from row0merge.h.  Make many functions static
in row0merge.c.

cmp_rec_rec_simple(): A new comparison function.

dict_index_get_min_size(): New function.

OS_FILE_FROM_FD(fd): A macro for converting from int to os_file_t.

rec_convert_dtuple_to_rec_comp(): Make the interface lower-level.

rec_get_converted_size_comp(): Return also extra_size.

UT_SORT_FUNCTION_BODY(): Remove reference to an obsolete test program.

row_rec_to_index_entry_low(): New function.

row0merge.c: Implement merge sort based on file streams instead of
fixed-size blocks.  Sort the small blocks as arrays of dfield_t*,
because it is faster than invoking rec_get_offsets() for every
comparison.

8b566bbb61 branches/zip: Clean up.

rec_init_offsets(): Remove bogus comment.

fbe4fe6022 branches/zip: Remove the casts introduced in r920 and r925. Replace the
accessors returning pointers with macros that preserve const qualifiers.
In UNIV_DEBUG builds, retain the accessors and cast away constness there.

dfield_get_type(), dfield_get_data(), dtuple_get_nth_field(),
dict_table_get_nth_col(), dict_table_get_sys_col(): Implement as macro
unless #ifdef UNIV_DEBUG.

rec_get_nth_field(): Replace with rec_get_nth_field_offs() that does not
do pointer arithmetics.  Implement rec_get_nth_field() as a macro.

8f07794024 branches/zip: Introduce const qualifiers to many read-only parameters
and modify some functions to return const pointers.  Add const qualifiers
to local variable declarations or casts to remove the const qualifier
in those places where write access is needed.
