For PR60531, GCC wrongly rejects function templates with explicitly
specified template arguments as overloaded. They are resolved by
resolve_nondeduced_context, which is normally called by
cp_default_conversion through decay_conversion, but the latter have
extra effects making them unusable here. Calling the former directly
does work.

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
generated.

The cxx_eval_increment_expression hunk is less important, but it's an easy
tweak; we only use the MODIFY_EXPR to evaluate it, so after that it's
garbage.

From-SVN: r271895

    
    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.

    When the runtime collects a stack trace to associate it with some
    profiling event (mem alloc, mutex, etc) there is a skip count passed
    to runtime.Callers (or equivalent) to skip some known count of frames
    in order to get to the "interesting" frame corresponding to the
    profile event. Now that the profiling mechanism uses lazy fixup (when
    removing compiler artifacts like thunks, morestack calls etc), we also
    need to move the frame skipping logic after the fixup, so as to insure
    that the skip count isn't thrown off by these artifacts.

    This requires tracking all references to unexported variables, so that
    we can make them global symbols in the object file, and can export
    them so that other compilations can see the right definition for their
    own inline bodies.
    
    This introduces a syntax for referencing names defined in other
    packages: a <pNN> prefix, where NN is the package index.  This will
    need to be added to gccgoimporter, but I didn't do it yet since it
    isn't yet possible to create an object for which gccgoimporter will

Improve the fix for PR64242.  Various optimizations can change a memory
reference into a frame access.  Given there are multiple virtual frame pointers
which may be replaced by multiple hard frame pointers, there are no checks for
writes to the various frame pointers.  So updates to a frame pointer tends to
generate incorrect code.  Improve the previous fix to also add clobbers of
several frame pointers and add a scheduling barrier.  This should work in most
cases until GCC supports a generic "don't optimize across this instruction"
feature.

Bootstrap OK. Testcase passes on AArch64 and x86-64.  Inspected x86, Arm,

A dynamic linker with lazy binding support may need to handle vector PCS
function symbols specially, so an ELF symbol table marking was
introduced for such symbols.

Function symbol references and definitions that follow the vector PCS
are marked in the generated assembly with .variant_pcs and then the
STO_AARCH64_VARIANT_PCS st_other flag is set on the symbol in the object
file.  The marking is propagated to the dynamic symbol table by the
static linker so a dynamic linker can handle such symbols specially.

For this to work, the assembler, the static linker and the dynamic
linker has to be updated on a system.  Old assembler does not support
the new .variant_pcs directive, so a toolchain with old binutils won't
be able to compile code that references vector PCS symbols.

In previous standards it is undefined for a container and its allocator
to have a different value_type. Libstdc++ has traditionally allowed it
as an extension, automatically rebinding the allocator to the
container's value_type. Since GCC 8.1 that extension has been disabled
for C++11 and later when __STRICT_ANSI__ is defined (i.e. for
-std=c++11, -std=c++14, -std=c++17 and -std=c++2a).

Since the acceptance of P1463R1 into the C++2a draft an incorrect
allocator::value_type now requires a diagnostic. This patch implements
that by enabling the static_assert for -std=gnu++2a as well.

Wilco pointed out that when the Dot Product instructions are available we can use them
to generate an even more efficient expansion for the [us]sadv16qi optab.
Instead of the current:
        uabdl2  v0.8h, v1.16b, v2.16b
        uabal   v0.8h, v1.8b, v2.8b
        uadalp  v3.4s, v0.8h

we can generate:
      (1)  mov    v4.16b, 1
      (2)  uabd    v0.16b, v1.16b, v2.16b
      (3)  udot    v3.4s, v0.16b, v4.16b

Instruction (1) can be CSEd across multiple such expansions and even hoisted outside of loops,
so when this sequence appears frequently back-to-back (like in x264_r) we essentially only have 2 instructions
per sum. Also, the UDOT instruction does the byte-to-word accumulation in one step, which allows us to use
the much simpler UABD instruction before it.

This makes it a shorter and lower-latency sequence overall for targets that support it.

This patch fixes bug 90681.  It was caused by trying to SLP vectorize a non
groupped load.  We've fixed it by tweaking a bit the implementation: mark
masked loads as not vectorizable, but support them as an special case.  Then
the detect them in the test for normal non-groupped loads that was already
there.
