[AArch64] PR tree-optimization/90332: Implement vec_init<M><N> where N is a vector mode
This patch fixes the failing gcc.dg/vect/slp-reduc-sad-2.c testcase on aarch64
by implementing a vec_init optab that can handle two half-width vectors producing a full-width one
by concatenating them.
In the gcc.dg/vect/slp-reduc-sad-2.c case it's a V8QI reg concatenated with a V8QI const_vector of zeroes.
This can be implemented efficiently using the aarch64_combinez pattern that just loads a D-register to make
use of the implicit zero-extending semantics of that load.
Otherwise it concatenates the two vector using aarch64_simd_combine.
With this patch I'm seeing the effect from richi's original patch that added gcc.dg/vect/slp-reduc-sad-2.c on aarch64
and 525.x264_r improves by about 1.5%.

Also remove some reundant tests that are duplicates of another test
except for a target specifier of c++11. Those tests previously set
-std=gnu++11 explicitly but that was replaced globally with a target
specifier. These tests existed to verify that explicit instantiation
worked for both C++98 and C++11 modes, but now do nothing because both

Refactor SFINAE constraints on std::tuple constructors
Replace the _TC class template with the better-named _TupleConstraints
one, which provides a different set of member functions. The new members
do not distinguish construction from lvalues and rvalues, but expects
the caller to do that by providing different template arguments. Within
the std::tuple primary template and std::tuple<T1, T2> partial
specialization the _TupleConstraints members are used via new alias
templates like _ImplicitCtor and _ExplicitCtor which makes the
constructor constraints less verbose and repetitive. For example, where
we previously had:
template<typename... _UElements, typename
enable_if<
_TMC<_UElements...>::template
_MoveConstructibleTuple<_UElements...>()
&& _TMC<_UElements...>::template
_ImplicitlyMoveConvertibleTuple<_UElements...>()
&& (sizeof...(_Elements) >= 1),
bool>::type=true>
constexpr tuple(_UElements&&... __elements)
We now have:
template<typename... _UElements,
bool _Valid = __valid_args<_UElements...>(),
_ImplicitCtor<_Valid, _UElements...> = true>
constexpr
tuple(_UElements&&... __elements)
There are two semantic changes as a result of the refactoring:
- The allocator-extended default constructor is now constrained.
- The rewritten constraints fix PR 90700.

In the runtime there are specialized fast map routines for
certain kep types. This CL lets the compiler make use of these
functions, instead of always using the generic ones.
As we now generate multiple versions of map delete calls, to make
things easier we delay the expansion of the built-in delete
function to flatten phase.

compiler: statically allocate constant interface data
When converting a constant to interface, such as interface{}(42)
or interface{}("hello"), if the interface escapes, we currently
generate a heap allocation to hold the constant value.
This CL changes it to generate a static allocation instead, as
the gc compiler does. This reduces allocations in such cases.

We want to evaluate the arguments to a call before looking into the cache so
that we have constant values, but if we then find the call in the cache we
end up with a TREE_LIST that we don't end up using; in highly recursive
constexpr evaluation this ends up being a large proportion of the garbage

compiler, runtime, reflect: generate unique type descriptors
Currently, the compiler already generates common symbols for type
descriptors, so the type descriptors are unique. However, when a
type is created through reflection, it is not deduplicated with
compiler-generated types. As a consequence, we cannot assume type
descriptors are unique, and cannot use pointer equality to
compare them. Also, when constructing a reflect.Type, it has to
go through a canonicalization map, which introduces overhead to
reflect.TypeOf, and lock contentions in concurrent programs.
In order for the reflect package to deduplicate types with
compiler-created types, we register all the compiler-created type
descriptors at startup time. The reflect package, when it needs
to create a type, looks up the registry of compiler-created types
before creates a new one. There is no lock contention since the
registry is read-only after initialization.
This lets us get rid of the canonicalization map, and also makes
it possible to compare type descriptors with pointer equality.
