[Flang][Driver] Override -ffast-math floating point contraction with -ffp-contract= (#213574)
This patch allows overriding the floating point contract settings
implied by -ffast-math by explicitly specifying -ffp-contract=. The
final floating point contract mode follows the usual last-flag-wins
behavior. In addition, -fno-fast-math only cancels the effects of
-ffast-math and preserves any explicitly specified -ffp-contract=
setting.
A warning is emitted when an explicit -ffp-contract= option overrides
the floating point contract mode implied by -ffast-math.
This behavior is consistent with Clang.
[CIR] Record target-cpu and target-features on function declarations (#214986)
A function declaration carried no CPU or feature attributes. CIRGen set
them from `setNonAliasAttributes`, which runs only for a definition,
where classic CodeGen sets them from `ConstructAttributeList` for a
declaration too. We now set them properly in `constructAttributeList`
alongside the other non-call-site attributes.
Recording them on a declaration exposes a second bug. When a function is
declared first and defined later with a `target` attribute,
`setNonAliasAttributes` wrote the definition's values over the
declaration's rather than replacing them, so a `tune-cpu` that the
`target` attribute suppresses survived. It now clears the three
attributes before writing, which is safe because
`getCPUAndFeaturesAttributes` resolves the most recent declaration, so
its result supersedes anything an earlier one wrote.

lit/reports.py: Make Py3.8-compatible (for #211066) (#215554)
I know py3.8 is slightly old. That said;
- llvm/CMakeLists.txt restricts the bottom version as 3.8
- This is not a functionally-critical change
I won't object further discussions if version upgrade would be required.
[CIR] Avoid folding non-integer constants as integer casts (#214551)
CIRGen may produce undef constants while recovering from NYI builtin
lowering. When such a value feeds an implicit integral cast,
CastOp::fold currently treats the source as an integer constant solely
because it is a cir.constant, then calls getIntValue() and crashes.
Added a check for the constant to see if the payload is actually an
IntAttr before folding the cast. If it is not, return the cast unfolded.
Added a regression test covering an unimplemented __builtin_stdc_* call
whose undef result was implicitly being cast to integer by CastOp::fold.

[orc-rt] SPS serialization: SPSExecutorAddrRange <-> span<T> (#215693)
Allows a memory range to be sent as an SPSExecutorAddrRange by the
controller and received as a span<T> by the executor, so handlers can
take a span directly rather than converting from an ExecutorAddrRange
themselves.
The wire format is identical to the existing ExecutorAddrRange
serialization -- a (Start, End) address pair -- so the two are
interchangeable in either direction.
Note that this transmits the span's bounds, not its contents; that
distinguishes it from the existing SPSSequence<char> / span<const char>
serialization, which copies the bytes.
Since the address pair arrives as untrusted wire data, deserialization
rejects inverted ranges, addresses that don't fit in uintptr_t, and
lengths that aren't a whole number of elements, rather than constructing
an out-of-bounds span.
