insts.

If the vectorizable GEP node is built, which should not be scheduled,
and at least one node is a non-gep instruction, need to insert the
vectorized instructions before the last instruction in the list, not
before the first one, otherwise the instructions may be emitted in the
wrong order.

The AOK_SizeDirective part from 5b37c181
(2014-08) seems unneeded nowadays (the root cause has likely been fixed
elsewhere). The part abuses that `call dword ptr foo` assembles the same way as `call
foo` in Intel syntax, which is going to be fixed (changed) by D149579.

The generated object files for
CodeGen/ms-inline-asm{,-functions,-variables,-static-variable}.c and

The asm in a naked function may reasonably expect the argument registers and the
return address register (if present) to be live.

When using -pg and -finstrument-functions, functions are instrumented by adding
a function call to `_mcount/__cyg_profile_func_enter/__cyg_profile_func_enter_bare`/etc,
which will clobber these registers. If the return address register is clobbered,
the function will be unable to return to the caller, possibly causing an
infinite loop.

```
__attribute__((naked)) void g() {
#if defined(__arm__)
  __asm__("bx lr");
#else
  __asm__("ret");
#endif
}

int main() { g(); }
```

It seems that the only one reasonable way to handle the combination is to
disable instrumenting for naked functions.

hlfir.assign, in general, ends up calling the Assign runtime that asserts
that the types of LHS and RHS match. In case of implicit logical<->integer
conversions (allowed as an extension) the operands of hlfir.assign
have non-matching types. This change makes sure that the lowering
produces explicit type cast (either as a scalar fir.convert or
as a hlfir.elemental producing array expression).

Add a callback from interception to allow asan on Windows to produce
better error messages. If an unrecoverable error occured when
intercepting functions, print a message before terminating.

Additionally, when encountering unknown instructions, a more helpful
message containing the address and the bytes of the unknown instruction
is now printed to help identify the issue and make it easier to propose
a fix.

Do not treat unknown instructions as a fatal error. In most cases,
failure to intercept a function is reported by the caller, though
requires setting verbosity to 1 or higher to be visible.

The i686-w64-windows-gnu target does not use SEH (which MSVC uses),
but DWARF-2 exception handling or possibly sjlj depending on the
toolchain build options. On this target we have to actually intercept
functions in libc++ and libunwind which handles throwing exceptions.
This fixes the `TestCases/intercept-rethrow-exception.cpp` test.

The x86_64-w64-windows-gnu target already works because it uses SEH
which is handled by intercepting RaiseException, so this change does not
affect x86_64.

expansions like the trip count. This preheader block is disconnected
at the moment, as the bypass blocks of the skeleton are not yet modeled
in VPlan.

The preheader block is executed before skeleton creation, so the SCEV
expansion results can be used during skeleton creation. At the moment,
the trip count expression and induction steps are expanded in the new
preheader. The remainder of SCEV expansions will be moved gradually in
the future.

D147965 will update skeleton creation to use the steps expanded in the
