Fangrui Song 423cb321df [ELF] Special case --shuffle-sections=-1 to reverse input sections 
If the number of sections changes, which is common for re-links after
incremental updates, the section order may change drastically.

Special case -1 to reverse input sections. This is a stable transform.
The section order is more resilient to incremental updates.  Usually the
code issue (e.g. Static Initialization Order Fiasco, assuming pointer
comparison result of two unrelated objects) is due to the relative order
between two problematic input files A and B.  Checking the regular order
and the reversed order is sufficient.
