i686-pc-linux-gnu, all languages except Ada/treelang.

As I wrote on gcc, I don't think I can be blamed on this.  The bugs are not
in the code I touched, but only in the code I enabled.  All I can do is
disabling -frename-registers on the affected archs, as per the attached
patch disable-ada-rename-regs.patch.

Also, I guess would have been found earlier if the Ada testsuite had tested
all optimization levels instead of -O2 only (and it used to be -O0, which
seems really strange to me!).  Can you please try the attached
ada-testsuite.patch on a two-three days old gcc, on Linux/x86-64 and/or
Linux/ia64?

Ok to commit both patches?

Paolo
