3.3.2 bug fix list, 2nd draft

[Joe Buck <jbuck at synopsys dot com>]

Here's draft 2 of the bug list for the 3.3.2 release notes.  If
there are additional fixes, please let me know -- I am relying on
the Bugzilla target milestone field, so if it is set incorrectly,
I will miss the bug.  Suggestions for better descriptions are also
welcome.

Added in this version: 8656 10147 11637 11740 12215 12236 12344 12490

Also, Rob Brown asked me to give some publicity to the fact that 10834,
which caused problems on ARM, was fixed in 3.3.1 and not mentioned in the
3.3.1 release notes.  Thanks to the fix, 3.3.1 (and .2) can now generate
valid code for interrupt handlers on ARM.

The following are not in any shipped gcc (they were introduced in CVS
after 3.3.1 and then fixed), though distros that ship snapshots
(e.g. Debian unstable) might have seen them:

12223 [3.3.2 regression] Compiler generates infinite loop
12248 .hidden detection now broken after recent commit
12328 New bootstrap failure on 3.3 branch
12406 g++.dg/parse/parameter-declaration-1.C fails

And here is the list:
