D front-end changes:
- Import dmd v2.099.1-beta.1.
- The address of NRVO variables is now stored in scoped closures
when they have nested references.
- Using `__traits(parameters)' in foreach loops now always returns
the parameters to the function the foreach appears within.
Previously, when used inside a `foreach' using an overloaded
`opApply', the trait would yield the parameters to the delegate.
- The deprecation period of unannotated `asm' blocks has been ended.
- The `inout' attribute no longer implies the `return' attribute.
- Added new `D_PreConditions', `D_PostConditions', and
`D_Invariants' version identifiers.

Phobos changes:
- Import phobos v2.099.1-beta.1.
- `Nullable' in `std.typecons' can now act as a range.
- std.experimental.logger default level changed to `info' instead of
`warning'.

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

this to have trickled down into enough releases.

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

* gcc.c (driver_handle_option): Set -static-libphobos as always valid.

Depending on the permutation of CPU, OS version and shared/non-

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.

* 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.

By default, D run-time has a top level exception handler to catch
anything that was uncaught by user code. However when the

information about the exception.
