Following up on the fix for PR99914, when testing on MinGW, it was found
not to support weak in the same way as on ELF or Mach-O targets.
So the linkage has been reverted back to COMDAT for that target, however
in order to properly support overriding functions and variables, all
declarations with external linkage must be put on COMDAT. For this a
new target hook has been added to control the behavior.

The default linkage of templates in the D language is now DECL_WEAK
instead of DECL_ONE_ONLY, if supported. This better matches the
expected override semantics of template symbols compiled to object code.
For example:
module rt.config;
template rt_flag()
{
pragma(mangle, "rt_flag") __gshared bool rt_flag = true;
}
module main;
extern(C) __gshared bool rt_flag = false;
The above currently does not succeed in linking due to there being
multiple definitions of `rt_flag' in different sections that aren't
considered mergeable.
The compiler flag enabling toggling of this has been given a clearer
named `-fweak-templates', which distinguishes itself from G++ `-fweak',
which is intended only for testing.

In the lowering of `bt*' intrinsics, some integer constants had
mismatched types, and bitsize was set to the wrong value.

Adds code generation for generating a temporary for, and pre-filling
struct and array literals with zeroes before assigning, so that
alignment holes don't cause objects to produce a non-deterministic hash
value. A new field has been added to the expression visitor to track
whether the result is being generated for another literal, so that
memset() is only called once on the top-level literal expression, and
not for nesting struct or arrays.

Both array concat and array new expressions wrapped any temporaries
created into a BIND_EXPR. This does not work if an expression used to
construct the result requires scope destruction, which is represented by
a TARGET_EXPR with a clean-up, and a CLEANUP_POINT_EXPR at the
location where the temporaries logically go out of scope. The reason
for this not working is because the lowering of cleanup point
expressions does not traverse inside BIND_EXPRs to expand any gimple
cleanup expressions within.
The use of creating BIND_EXPR has been removed at both locations, and
replaced with a normal temporary variable that has initialization
delayed until its address is taken.

Named arguments were being passed around by invisible reference, just
not variadic arguments. There is a need to de-duplicate the routines
that handle declaration/parameter promotion and reference checking.
However for now, the parameter helper functions have just been renamed
to parameter_reference_p and parameter_type, to make it more clear that
it is the Parameter equivalent to declaration_reference_p and
declaration_type.
On writing the tests, a forward-reference bug was discovered on x86_64
during va_list type semantic. This was due to fields not having their
parent set-up correctly.

prototypes. This allows the ability to set user defined attributes on

xcallocator>::find_slot_with_hash
This patch fixes LTO bug with the D front-end. As DECL_ASSEMBLER_NAME
is set on the TYPE_DECL, so TYPE_CXX_ODR_P must also be set on the type.
The addition of merge_aggregate_types is not strictly needed now, but it

templated types could be sent more than once to the D code generator.

Currently, the druntime and phobos unittests are compiled as a separate
check program, then ran by the libphobos.unittest/unittest.exp script.
As PR d/89255 notes, this process lacks proper multilib handling.
As a first step, a new internal option that instructs the compiler to
put the reference to all unittest functions in another symbol has been
added. This will allow each module to be compiled separately as a
