For context, LocIdx is a key/index number for machine locations, so that we
can describe locations as a single integer and ignore whether they're on
the stack, in registers or otherwise. Back when InstrRefBasedLDV was added,
I happened to bake in a "special" zero number for various reasons, which
Vedant identified as undesirable in this review comment:
https://reviews.llvm.org/D83047#inline-765495 . I subsequently removed that
special zero number, but it looks like I didn't delete this assertion at
the time, which assumes that a zero LocIdx is invalid.
The attached test shows that this assertion is reachable on valid code --
on x86 $rsp always gets the LocIdx number zero, and if you transfer a
variable value into it, InstrRefBasedLDV crashes on that assertion. The
code might be a bit wild to be storing variables to $rsp like that, however
we shouldn't crash on it.

[flang] Refine output file generation
This patch refactors the file generation API in Flang's frontend driver.
It improves the layering between `CreateDefaultOutputFile`,
`CreateOutputFile` (`CompilerInstance` methods) and their various
clients.
List of changes:
* Rename `CreateOutputFile` as `CreateOutputFileImpl` and make it
private. This method is an implementation detail.
* Instead of passing an `std::error_code` out parameter into
`CreateOutputFileImpl`, have it return Expected<>. This is a bit shorter
and more idiomatic LLVM.
* Make `CreateDefaultOutputFile` (which calls `CreateOutputFileImpl`)
issue an error when file creation fails. The error code from
`CreateOutputFileImpl` is used to generate a meaningful diagnostic
message.
* Remove error reporting from `PrintPreprocessedAction::ExecuteAction`.
This is only for cases when output file generation fails. This is
handled in `CreateDefaultOutputFile` instead (see the previous point).
* Inline `AddOutputFile` into its only caller,
`CreateDefaultOutputFile`.
* Switch from `lvm::buffer_ostream` to `llvm::buffer_unique_ostream>`
for non-seekable output streams. This simplifies the logic in the driver
and was introduced for this very reason in [1]
* Moke sure that the diagnostics from the prescanner when running `-E`
(`PrintPreprocessedAction::ExecuteAction`) are printed before the actual
output is generated.
* Update comments, add test.

libclc: Fix rounding during type conversion
The rounding during type conversion uses multiple conversions, selecting
between them to try to discover if rounding occurred. This appears to
not have been tested, since it would generate code of the form:
float convert_float_rtp(char x)
{
float r = convert_float(x);
char y = convert_char(y);
[...]
}
which will access uninitialised data. The idea appears to have been to
have done a char -> float -> char roundtrip in order to discover the
rounding, so do this.
Discovered by inspection.

D107156 and D107320 are not sufficient when OpenMP is built as llvm runtime

We could limit the dependency to cases where libomptarget/plugins are really

negligible and postponing the build of OpenMP runtime after the dependencies
are ready seems reasonable.

[AArch64][GlobalISel] Add G_VECREDUCE fewerElements support for full scalarization.
For some reductions like G_VECREDUCE_OR on AArch64, we need to scalarize
completely if the source is <= 64b. This change adds support for that in
the legalizer. If the source has a pow-2 num elements, then we can do
a tree reduction using the scalar operation in the individual elements.
Otherwise, we just create a sequential chain of operations.
For AArch64, we only need to scalarize if the input is <64b. If it's great than
64b then we can first do a fewElements step to 64b, taking advantage of vector
instructions until we reach the point of scalarization.
I also had to relax the verifier checks for reductions because the intrinsics
support <1 x EltTy> types, which we lower to scalars for GlobalISel.
