Fangrui Song 16c30c3c23 [ELF] Change --shuffle-sections=<seed> to --shuffle-sections=<section-glob>=<seed> 
`--shuffle-sections=<seed>` applies to all sections.  The new
`--shuffle-sections=<section-glob>=<seed>` makes shuffling selective.  To the
best of my knowledge, the option is only used as debugging, so just drop the
original form.

`--shuffle-sections '.init_array*=-1'` `--shuffle-sections '.fini_array*=-1'`.
reverses static constructors/destructors of the same priority.
Useful to detect some static initialization order fiasco.

`--shuffle-sections '.data*=-1'`
reverses `.data*` sections. Useful to detect unfunded pointer comparison results
of two unrelated objects.

If certain sections have an intrinsic order, the old form cannot be used.
