compiler: ensure evaluation order in type hash/eq functions

    The type hash and equality functions are generated after the
    order_evaluations pass. They may contain shortcut operators and
    Set_and_use_temporary_expressions (e.g. from lowering a
    Binary_exprssion) that need to be ordered. Run order_evaluations
    and remove_shortcuts on these functions. (The hash functions
    may be fine, but to be on the safe side we run on them anyway.
    We do need to run on the equality functions.)

    A Set_and_use_temporary_expression is effectively an assignment,
    so it needs to be ordered. Otherwise if we insert a temporary
    statement before it, we may get wrong evaluation order.

    A test case is CL 185818.

    Fixes golang/go#33062.

Define std::atomic_ref and std::atomic<floating-point> for C++20

This adds the new atomic types from C++2a, as proposed by P0019 and
P0020. To reduce duplication the calls to the compiler's atomic
built-ins are wrapped in new functions in the __atomic_impl namespace.
These functions are currently only used by std::atomic<floating-point>
and std::atomic_ref but could also be used for all other specializations
of std::atomic.

Additionally, errors on constructs not supported in SPARK are

[Ada] New Repinfo.Input unit to read back JSON representation info.

For some time the Repinfo unit has been able to output the
representation information in the JSON data interchange format in
addition to the usual text and binary formats.

The new Repinfo.Input unit makes it possible to read back this
information under this format and make it available to clients, the main
one being ASIS.

The big advantage of using this approach over manipulating a binary blob
is that the writer and the reader of the JSON representation need not be
binary compatible, i.e. in practice need not be the same version of the
compiler or ASIS for the same target.

The patch also adds a -gnatd_j switch to read back the information in
the compiler itself, which makes it easy to keep the writer and the
reader in sync using only one tool, namely the compiler.  The typical
usage is:

  gcc -c p.ads -gnatR4js
  gcc -c p.ads -gnatd_j

to exercise respectively the writer and the reader from the compiler.

compiler: finalize methods when importing types

    This patch changes the compiler to be more aggressive about finalizing
    methods on imported types, to avoid problems with interface types that
    are imported but remain unreachable until a later stage in the compilation.

    The normal pattern prior to this change was that the import process would
    leave imported interface types alone, and rely on Gogo::finalize_methods
    to locate and finalize all interface types at a later point. This way
    of doing things was not working in all cases due to the fact that we can
    import an interface type that is only reachable from the body of an
    inlinable function, meaning that we can't "find" the type during
    the methods finalize phase.

    The importer's Import::read_types() now makes a pass over all imported
    types to finalize methods on any newly imported type, which takes care
    of the issue.

    New test case for this problem in CL 185517.

[Ada] Spurious run-time error with 64-bit modular types

As a lexical element an integer literal has type Universal_Integer, i.e
is compatible with any integer type. This is semantically consistent and
simplifies type checking and subsequent constant folding when
applicable.  An exception is caused by 64-bit modular types, whose upper
bound is not representable in a non-static context that will use 64-bit
integers at run-time. For such cases we need to preserve the information
that the analyzed literal has that modular type. For simplicity we
preseve the information for all integer literals that result from a
modular operation.  This happens after prior analysis (or construction)

[Ada] Crash on aggregate for limited type in extended return

This patch fixes a compiler abort on an extended return statement whose
expression is an aggregate (to be built in place) for a discriminated
record with a limited component. The build-in-place mechanism creates an
access type and a renaming declaration  through which individual
components are assigned. The renamed object is constrained because it is
limited, and the renaming declaration does not need to create a local
subtype indication for it, which may lead to type mismatches in the
back-end, and is in any case redundant. This patch extends this
optimization to the case of records that are limited only because of a
limitied component, and not because they are explicit declared limited.

[aarch64]: redefine aes patterns

This first patch removes aarch64 usage of the aese/aesmc and aesd/aesimc
fusions (i.e. aes fusion) implemented in the scheduler due to unpredictable
behaviour observed in cases such as:
- when register allocation goes bad (e.g. extra movs)
- aes operations with xor and zeroed keys among interleaved operations

A more stable version should be provided by instead doing the aes fusion
during the combine pass. Since the aese and aesd patterns have been
rewritten as encapsulating a xor operation, the existing combine fusion
patterns have also been updated. The purpose is to simplify the need of
having additional combine patterns for cases like the ones below:

For AESE (though it also applies to AESD as both have a xor operation):

    data = data ^ key;
    data = vaeseq_u8(data, zero);
    ---
    eor         v1.16b, v0.16b, v1.16b
    aese        v1.16b, v2.16b

Should mean and generate the same as:

    data = vaeseq_u8(data, key);
    ---
    aese        v1.16b, v0.16b
