Hi

Using the heap profiler 'valgrind --tool=massif vim'
I saw 135,536 bytes allocated from here:

| | ->03.74% (135,536B) 0x43D7D1: dict_alloc (eval.c:6977)
| | | ->03.69% (133,816B) 0x43E360: get_dict_tv (eval.c:7471)
| | | | ->03.69% (133,816B) 0x43A8AD: eval7 (eval.c:5081)
| | | |   ->03.69% (133,816B) 0x43A34C: eval6 (eval.c:4802)
| | | |     ->03.69% (133,816B) 0x439E9C: eval5 (eval.c:4618)

eval.c:

6977     d = (dict_T *)alloc(sizeof(dict_T));

Adding printf(), I see that sizeof(dict_T) is 344 bytes
on Linux x86_64. Attached patch reorders fields in
that struct to reduce padding and brings sizeof(dict_T)
to 336 bytes. It thus saves :

135536 - 135536/344*336 = 3152 bytes

It's not much but it's simple and several of such other
changes can add up.

Regards
Dominique
