Improve code generation in opj_t1_dec_clnpass()
...
Add a opj_t1_dec_clnpass_step_only_if_flag_not_sig_visit() method that
does the job of opj_t1_dec_clnpass_step_only() assuming the conditions
are met. And use it in opj_t1_dec_clnpass(). The compiler generates
more efficient code.

Fix issue 135
The fix is legal regarding the standard but I did not manage to find out if it covers a bug in opj_t2_read_packet_data or if the file is corrupted

Fix negative shift left reported by UBSan ( #758 )
...
Follow-up of #757
This shall have no performance impact on 2’s complement machine where
the compiler replaces the multiplication by power of two (constant) by
a left shift.
Verified at least on MacOS Xcode 7.3, same assembly generated after fix.
