[Hexagon] Fix KCFI check truncating type id (#211854)
The KCFI indirect-call check is lowered directly to MCInst in the
Hexagon AsmPrinter. It omitted the constant-extender, causing
mismatches.
Packet canonicalization is how we should apply constant extenders,
duplex, compounds, etc.

[RISCV] Fix prefetch ADDI-adjustment range upper bound (#215985)
SelectAddrRegImmLsb00000 folds a large constant offset into an ADDI plus
a simm12_lsb00000 prefetch immediate. The positive range [2017, 4065]
overflowed simm12 at the top end: CVal - 2016 reaches 2048/2049,
producing an invalid ADDI. Narrow it to 4063; 4064/4065 now fall through
to selectConstantAddr instead.

[DWARFLinker] Consider module units when creating the type unit (#215731)
The parallel linker creates the artificial type unit only when some
compile unit uses an ODR language, but it looks for that language in the
compile units of the object files alone. A clang module unit decides its
own ODR availability from its own DW_AT_language, so a module built as
C++ or ObjC++ imported from an object file whose units are all C, ObjC
or Swift places DIEs in the type table which does not exist, asserting
in CompileUnit::cloneDIE and dereferencing null without assertions.
Scan the languages of the module units as well, so a module which
deduplicates types always has a type unit to hold them.

[RISCV] Avoid pre-RA Zilsd pairs with same src/dst registers (#215575)
The pre-RA Zilsd optimizer previously allowed a special case for stores
where both source operands were the same vreg if that vreg was defined
by COPY $x0. This assumes register allocation will preserve the value as
x0, but that is not guaranteed. The vreg can be allocated to a normal
GPR, producing an invalid pair.

[DWARFLinker] Keep module type definitions in the parallel linker (#215435)
A Clang module compile unit carries the only definitions of the types
its module owns. No definition in it is reachable from a live address.
Similar to the classic linker, we need to mark everything as kept.

[lldb] Fix incorrect Python property bindings in SBExtensions. (#215283)
Several Python property definitions in the SB extension interface files
were incorrectly copy-pasted during the
["Don't use SWIG internals
refactor"](https://github.com/llvm/llvm-project/commit/89b658428bae3b749f174ca79f0fe390451d8f69)
causing properties to shadow earlier definitions instead of exposing new
functionalities.
Rename each duplicate to its intended property name and wire it to the
correct underlying method.
Add add new API tests to cover the issue.
- SBModule: compile_unit -> section.
- SBType: is_function -> is_reference.
- SBTypeSummary is_function_code -> is_function_name.

[Hexagon] Fix unusable SCS reg, make it selectable (#213820)
SCS hardcoded r19 as the shadow call stack pointer and required
-ffixed-r19. That was the wrong register to pick: r19 is precisely the
one the intended consumers cannot give up, so the feature was unusable
in practice.
* The Hexagon Linux kernel already reserves r19 for its thread-info
pointer (arch/hexagon/Makefile: "TIR_NAME := r19", documented there as
not configurable because it is hard-coded in several files).
* hexagon-hypervisor reserves r20-r28 (kernel/CMakeLists.txt), with r28
bound to a register global (H2K_gp).
That leaves h2 only r16-r19, so no single hardcoded choice can serve
both consumers.
Intersecting that with the callee-saved regs leaves r1{6,7,8}. So the
new default is r18.

[flang] To issue error message for unsupported usage of vector type. (#215248)
As discussed in PR #214219, we don't plan to support any usage that
requires runtime descriptor for vector type object.
Flang has already disallowed ALLOCATABLE, POINTER, ASSUMED-SHAPE and
ASSUMED-RANK for vector types.
The test reducer posted by @eugeneepshteyn should also be flagged by the
compiler as an error.
This PR is to add semantic check for that case. It covers
1. Vector type declaration statement that has ALLOCATABLE or POINTER
attribute.
2. ALLOCATE statement where SOURCE= or MOLD= has a vector type object.
3. Auto-allocation intrinsic assignment where the RHS is a vector type
object.
4. A vector type object being used as an argument of SAME_TYPE_AS or
EXTENDs_TYPE_OF.
5. A vector type object being used as the `dtv` argument of a UDIO.
6. A vector type object being used as the argument of `CLASSOF`.
