libphobos is currently only enabled on Solaris/x86 with gas. As
discovered when gdc was switched to the dmd frontend, this initially
broke bootstrap for the other Solaris configurations.
However, it's now well possible to enable it both for Solaris/x86 with
as and Solaris/SPARC (both as and gas) since the original problems (x86
as linelength limit, among others) are long gone.
The following patch does just that.
Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11 (both as and
gas) with gdc 9.3.0 (x86) resp. 9.4.0 (sparc, configured with
--enable-libphobos) as bootstrap compilers.

This is the library fix for PR103520 that also prevents the garbage
collector from releasing live memory. However this requires that the
host compiler has been patched with this fix, so the GC will remain
disabled in the D front-end for now until enough time has passed for
this to have trickled down into enough releases.
libphobos/ChangeLog:

missing ControlState variable for AArch64.
In the gdc driver, this takes the previous fix for the Darwin D
bootstrap, and extends it to the -static-libphobos option as well.
Rather than pushing the -static-libphobos option back onto the command
line, the setting of SKIPOPT is instead conditionally removed. The same
change has been repeated for -static-libstdc++ so there is now no need
to call generate_option to re-add it.
In the gcc driver, -static-libphobos has been added as a common option,
validated, and a new outfile substition added to config/darwin.h to
correctly replace -lgphobos with libgphobos.a.
gcc/ChangeLog:
* common.opt (static-libphobos): Add option.
* config/darwin.h (LINK_SPEC): Substitute -lgphobos with libgphobos.a
when linking statically.
* gcc.c (driver_handle_option): Set -static-libphobos as always valid.
gcc/d/ChangeLog:
* d-spec.cc (lang_specific_driver): Set SKIPOPT on -static-libstdc++
and -static-libphobos only when target supports LD_STATIC_DYNAMIC.
Remove generate_option to re-add -static-libstdc++.
libphobos/ChangeLog:
* testsuite/testsuite_flags.in: Add libphobos library directory as
search path to --gdcldflags.
Depending on the permutation of CPU, OS version and shared/non-
shared library inclusion, we get can get two warnings from the
external tools (ld64, dsymutil) which are not actually GCC issues
but relate to the external tools. These are alrrady pruned in
the main testsuite, this adds them to the library.

As of macOS 11, libunwind now requires more stack space than 16k, so
default to a larger stack size. This is only applied to X86 as the
PAGESIZE is still 4k, however on AArch64 it is 16k.
libphobos/ChangeLog:
* libdruntime/core/thread/fiber.d (defaultStackPages): Increase size
on OSX X86_64 targets.
Fixes a EXC_BAD_ACCESS issue seen on Darwin when the libphobos DSO gets
unloaded. Based on reading libgcc's emutls implementation, as it
doesn't call __gthread_key_delete directly, neither should libphobos.
libphobos/ChangeLog:
* libdruntime/gcc/emutls.d (emutlsDestroyThread): Don't remove entry
from global array.
(_d_emutls_destroy): Don't call __gthread_key_delete.
The _Unwind_Exception struct had its alignment adjusted to 16-bytes,
however malloc() on Solaris X86 is not guaranteed to allocate memory
aligned to 16-bytes as well.

This is analogous to __gdc_personality, which ignores in-flight

By default, D run-time has a top level exception handler to catch
anything that was uncaught by user code. However when the
`rt_trapExceptions' flag is cleared, this handler would not be enabled,
and this termination would occur, aborting the program, but without any
information about the exception.
libphobos/ChangeLog:
* libdruntime/gcc/deh.d (_d_print_throwable): Declare.
(_d_throw): Print stacktrace before terminating program due to
uncaught exception.
The core.runtime module always overrides the default parameter value for
constructor calls. MaxAlignment is not required because a class can be
created on the stack with the `scope' keyword.

LibBacktrace on the stack.
* libdruntime/gcc/backtrace.d (FIRSTFRAME): Remove.
(LibBacktrace.MaxAlignment): Remove.
(LibBacktrace.this): Remove default initialization of firstFrame.
(UnwindBacktrace.this): Likewise.
For interoperability with C++ EH, the alignment should match, otherwise
