the implementation is known-broken for certain inputs,
the bugreport was up for a significant amount of timer,
and there has been no activity to address it.
Therefore, just completely rip out all of misexpect handling.
I suspect, fixing it requires redesigning the internals of MD_misexpect.
Should anyone commit to fixing the implementation problem,
starting from clean slate may be better anyways.
This reverts commit 7bdad08429,
and some of it's follow-ups, that don't stand on their own.
Summary:
Wasm currently does not fully handle exception specifications. Rather
than crashing,
- This treats `throw()` in the same way as `noexcept`.
- This ignores and prints a warning for `throw(type, ..)`, for a
temporary measure. This warning is controlled by
`-Wwasm-exception-spec`, which is on by default. You can suppress the
warning by using `-Wno-wasm-exception-spec`.

The built-in SVE types are supposed to be treated as opaque types.
This means that for initialisation purposes they should be treated
as a single unit, much like a scalar type.
However, as Eli pointed out, actually using "scalar" in the diagnostics
is likely to cause confusion, given the types are logically vectors.
The patch therefore uses custom diagnostics or generalises existing
ones. Some of the messages use the word "indivisible" to try to make
it clear(er) that these types can't be initialised elementwise.
I don't think it's possible to trigger warn_braces_around_(scalar_)init
for sizeless types as things stand, since the types can't be used as
members or elements of more complex types. But it seemed better to be
consistent with ext_many_braces_around_(scalar_)init, so the patch
changes it anyway.

I have a follow-on patch that uses an alternative wording for
ext_excess_initializers in some cases. This patch puts it and
a couple of related warnings under their own -W option in order
to avoid a regression in Misc/warning-flags.c.

It looks like it has been a while since the checked-in version of
DiagnosticsReference.rst was regenerated. I realise there probably
isn't any expectation that the checked-in version is kept up-to-date,
but now that the project is on github and the rst can be viewed directly
from the repo's web interface, it seemed worth having something a bit
more recent.

Fixes the sphinx warning:
tools/clang/docs/DiagnosticsReference.rst:7889: WARNING: Title underline
too short.
That I just introduced in r350877.

remark flags. For now I'm checking in a copy of the built documentation, but we
can replace this with a placeholder (as we do for the attributes reference
documentation) once we enable building this server-side.
