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.

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.

D attribute support has been updated to have a baseline parity with the
LLVM D compiler's own `ldc.attributes'.
The handler that extracts GCC attributes from a list of UDAs has been
improved to take care of some mistakes that could have been warnings.
UDAs attached to field variables are also now processed for any GCC
attributes attached to them.
The following new attributes have been added to the D front-end:
- @attribute("alloc_size")
- @attribute("used")
- @attribute("optimize")
- @attribute("restrict")
- @attribute("cold")
- @attribute("noplt")
- @attribute("target_clones")
- @attribute("no_icf")
- @attribute("noipa")
- @attribute("symver")
With convenience aliases in a new `gcc.attributes' module to match
the same naming convention as `ldc.attributes':
- @allocSize()
- @assumeUsed
- @fastmath
- @naked
- @restrict
- @cold
- @noplt
- @optStrategy()
- @polly
- @section()
- @target()
- @weak
The old gcc.attribute module has been deprecated, along with the removal
of the following attribute handlers:
- @attribute("alias"): Has been superseded by `pragma(mangle)'.
- @attribute("forceinline"): Renamed to always_inline.

D front-end changes:
- Explicit package visibility attribute is now always applied to
introducing scopes.
- Added `__traits(totype, string)' to convert mangled type string to an
existing type.
- Printf-like and scanf-like functions are now detected by prefixing
them with `pragma(printf)' for printf-like functions or
`pragma(scanf)' for scanf-like functions.
- Added `__c_wchar_t', `__c_complex_float', `__c_complex_double', and
`__c_complex_real' types for interfacing with C and C++.
- Template alias parameters can now be instantiated with basic types,
such as `int` or `void function()`.
- Mixins can now be used as types in the form `mixin(string) var'.
- Mixin expressions can take an argument list, same as `pragma(msg)'.
- Implement DIP1034, add `typeof(*null)' types to represent `noreturn'.
- `pragma(msg)' can print expressions of type `void'.
- It is now an error to use private variables selectively imported from
other modules. Due to a bug, some imported private members were
visible from other modules, violating the specification.
- Added new syntax to declare an alias to a function type using the
`alias' syntax based on the assignment operator.
- Function literals can now return a value by reference.
Phobos changes:
- Synchronize C bindings with the latest port fixes in upstream druntime.
- Added alias for a `noreturn' type in object.d
- Make use of the new `pragma(printf)' and `pragma(scanf)' pragmas, fix
all code that got flagged as being incorrect.
- Fixed code that relied on bugs in the D import package system.

The libgdruntime_convenience library was built with `-fversion=Shared',
but the libphobos part wasn't when creating the static library.
As there are no issues compiling in Shared code into the static library,
to avoid mismatches the flag is now always present when --enable-shared
is turned on. Libtool's compiler PIC D flag is now the combination of
compiler PIC and D Shared flags, and AM_DFLAGS passes `-prefer-pic' to

When libphobos is configured with --enable-cet, this adds extra fields
to the Fiber class to support the ucontext_t fallback implementation.
These fields get omitted when compiling user code unless they also used
`-fversion=CET' to build their project, which resulted in data being
overwritten from within swapcontext().
On reviewing the ucontext_t definitions, it was found that the shadow
stack fields were missing, and the struct size didn't match up on X32.
This has been fixed in upstream druntime and merged down here.

* libdruntime/config/x86/switchcontext.S: Include <cet.h> to
generate the CET marker for -fcf-protection.
Rather than implementing support within D runtime itself, use libc
getcontext/swapcontext functions if CET is enabled.
Removes whatever CET support was in the switchContext routine for x86
D runtime, along with setting version AsmExternal, so that the fallback
ucontext_t implementation is used, which is capable of doing shadow
stack handling.

This is the default in the upstream reference compiler, and can reduce
some confusion when comparing warning/error messages of gdc and dmd side
by side.
Merges libphobos with upstream druntime d05ebaad and phobos 021ae0df7.

When __CET__ is defined, <cet.h> should be included to add Intel CET
marker to object file and _CET_ENDBR should be placed at function entry
to indicate indirect branch target.
* libdruntime/config/x86/switchcontext.S: Include <cet.h> if
__CET__ is defined.
(_CET_ENDBR): New. Define if __CET__ is not defined.
(fiber_switchContext): Add _CET_ENDBR after .cfi_startproc.
Corrects a previous change made to the SPARC stdc bindings, and
backports PPC-related fixes. The library and language testsuite now
passes fully on powerpc64le-linux-gnu.

Adds a new test directive COMPILABLE_MATH_TEST, and support has been
added for it in gdc-convert-test so that they are skipped if phobos is
not present on the target.
Only change in D runtime is a small documentation fix.

* lib/gdc-utils.exp (gdc-convert-test): Add dg-skip-if for compilable
tests that depend on the phobos standard library.
* New core.math.toPrec templates have been added as an intrinsic.
Some floating point algorithms, such as Kahan-Babuska-Neumaier
Summation, require rounding to specific precisions. Rounding to
precision after every operation, however, loses overall precision in
the general case and is a runtime performance problem.
Adding these functions guarantee the rounding at required points in
the code, and document where in the algorithm the requirement exists.
* Support IBM long double types in core.internal.convert.
* Add missing aliases for 64-bit vectors in core.simd.
* RUNNABLE_PHOBOS_TEST directive has been properly integrated into the
D2 language testsuite.
