[trunk] PATCH: unique names for patches.

[Basile STARYNKEVITCH]

Hello All,

The attached patch (to trunk rev.138388) ensure that every opt_pass has 
a unique name (and this is checked when ENABLE_CHECKING thru an hash 
table of passes). The patch modify many passes name, or name (with a 
star) the previously anonymous passes.

The patch did bootstrap with .../configure '--enable-checks=all' 
'--disable-multilib' '--enable-languages=c,c++'
