GCC: Add a new option "-fstack-protector-strong"

This includes additional functions to be protected: those that
have local array definitions, or have references to local frame
addresses. This is a new option in GCC-4.9 that was relicensed
by Han Shen from Google under GPLv2 for OpenBSD.

gcc: Add support for -Wmissing-prototypes in C++

Support for warnings about missing prototypes in C++ was added by Apple
GCC (Radar 6261539). Most of the code crept into r260311 so it felt
natural to make use of it.

gcc: Add support for Apple's Block extension

Block objects [1] are a C-level syntactic and runtime feature. They
are similar to standard C functions, but in addition to executable
code they may also contain variable bindings to automatic (stack)
or managed (heap) memory. A block can therefore maintain a set of
state (data) that it can use to impact behavior when executed.

This port is based on Apple's GCC 5646 with some bugfixes from
Apple GCC 5666.3. It has some small differences with the support
in clang, which remains the recommended compiler.

Perhaps the most notable difference is that in GCC that __block
is not actually a keyword, but a macro. There will be workaround
for this issue in a near future. Other issues can be consulted in
the clang documentation [2]

For better compatiblity with Apple's GCC and llvm-gcc some related
fixes and features from Apple have been included. Support for the
non-standard nested functions in GCC is now off by default.

No effort was made to update the ObjC support since FreeBSD doesn't
carry ObjC in the base system, but some of the code crept in and
was more difficult to remove than to adjust.

GCC: bring back experimental support for amdfam10/barcelona CPUs.

Initial support for the AMD amdfam10 chipsets has been available in the
gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did
a backport of the amdfam10 support and made it available.

This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

Revert r236962 - Experimental amdfam10/barcelona support.

The patches are unexpectedly causing gcc to fail while
building ports/graphics/ImageMagick even when the cpu
flags are not used.

Reported by: Andreas Tobler

Add experimental support for amdfam10/barcelona from the GCC 4.3 branch.

Initial support for the AMD barcelona chipsets has been available in the
gcc43 branch under GPLv2 but was not included when the Core 2 support
was brought to the system gcc.

AMD and some linux distributions (OpenSUSE) did a backport of the amdfam10
support and made them available. Unfortunately this is still experimental
and while it can improve performance, enabling the CPUTYPE may break some
C++ ports (like clang).

Special care was taken to make sure that the patches predate the GPLv3
switch upstream.
