Following what is already performed for vector.reduce.fmin/fmax, this adds
lowering for the new vector.reduce.fminimum/fmaximum nodes to the SVE fminv
and fmaxv instructions via the existing FMINV_PRED/FMAXV_PRED nodes.

It has been reported to that the current clang  errors for, specifically,
static_assert in export contexts are a serious blocker to adoption of
modules in some cases.

There is also implementation divergence with GCC and MSVC allowing the
constructs mentioned below where clang currently rejects them with an
error.

The category of errors [for declarations in an exported context] is:
(unnamed, static_assert, empty and asm decls). These are now permitted
after P2615R1 which was approved by WG21 as a DR (and thus should be
applied to C++20 as well).

This patch removes these diagnostics and amends the testsuite accordingly.

This is just a cleanup commit, a follow up will make this way more
structured.

We now consistently use `CallBase::getCalledOperand` rather than
`getCalledFunction`, as we do not want the type checked performed by the
latter. This exposed various missing checks to handle mismatches
properly, but it is good to have them explicit now.

In a follow up we might want to flag certain calls as UB, but for now,
we allow everything to cut down on unexpected differences.

Partial progress towards replacing in-tree uses of
`Type::getPointerTo()`.

If `getPointerTo()` is used solely to support an unnecessary bitcast,
remove the bitcast.

These aren't detected during testing most of the time because the way we
are setting up mlir-opt and the fact that we always use func.func: it'll
trigger the load of the InlinerInterface extension for the FuncDialect which
itself loads these dialects unconditionally.

Without the changes from D153598.

Original commit message:

For the same reasons as D151284, this requires custom lowering of the
truncate libcall on hard float ABIs (the normal libcall code path is
used on soft ABIs).

The extend operation is implemented by a shift just as in the standard
legalisation, but needs to be custom lowered because i32 isn't a legal
type on RV64.

This patch aims to make the minimal changes that result in correct
codegen for the bfloat.ll tests.

This reverts commit 690b1c84.

Instead of creating an AA for an IR attribute we can first check if it
is implied/known. If so, we can save the time to create the AA, figure
out it is implied, fix it, and later manifest it in the IR
(redundantly). Other IR attributes can be added to the list in
`AA::hasAssumedIRAttr` later on, for now we support 8 different ones.

This will make it easier to create less trivial AAs in the future as we
can simply return `nullptr` rather than an AA with in invalid state.
