Denys Vlasenko c2a51b0cf1 bzip2: work around bad compiler optimization 
gc-6.1.1 x86_64:
function                                             old     new   delta
generateMTFValues                                    380     367     -13

gcc-4.3.1 386:
function                                             old     new   delta
inner_loop                                             -      41     +41
generateMTFValues                                    357     294     -63
------------------------------------------------------------------------------
(add/remove: 1/0 grow/shrink: 0/1 up/down: 41/-63)            Total: -22 bytes

gcc-6.3.0 386:
function                                             old     new   delta
inner_loop                                             -      36     +36
generateMTFValues                                    363     250    -113
------------------------------------------------------------------------------
(add/remove: 1/0 grow/shrink: 0/1 up/down: 36/-113)           Total: -77 bytes

The last case, gcc-6.3.0, runs almost 3 times faster after this change.
