gcc: Add support for label attributes and "unavailable" attribute.

Apple GCC has extensions to support for both label attributes and
an "unavailable" attribute. These are critical for objc but are
also useful in regular C/C++.

Apparently at least the label attributes might have found their way to
upstream GCC but the code doesn't seem available on the GPLv2 tree so
we are taking the code directly from Apple. To make this clearer we
are preserving the annoying "APPLE LOCAL" tags and the ChangeLogs
when they are available.

Revert r259619:
Fixes GCC libstdc++/29286

The fix seems to work for amd64 but causes segfaults on powerpc.
At this time gcc is much more important on powerpc than on amd64.

gcc: upstream alignment cleanups.

This solves GCC/32617 and contributes to reduce differences with
Apple's gcc42.

Complete some references in the ChangeLog while here.

FreeBSD uses unchanged versions of this files.

Use stock GCC versions on these files.

FreeBSD uses stock versions of these GCC files.

Use pure stock files.

Use the stock (3.1) version.

Use the stock [3.1-snap] file.

Use the stock file now.

Fix conflicts.

Fixed printf format errors. gcc should have a macro HOST_PTR_PRINTF_TYPE
to go with its HOST_PTR_PRINTF[_FORMAT], since if %p is wrong for the
format then `void *' is probably wrong for the type.

This commit was generated by cvs2svn to compensate for changes in r18334,
which included commits to RCS files with non-trunk default branches.

Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the
non-i386, non-unix, and generatable files have been trimmed, but can easily
be added in later if needed.

gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's
handy to have both available for reference for such little cost.

The freebsd-specific changes will then be committed, and once the dust has
settled, the bmakefiles will be committed to use this code.
