[Hexagon,Lanai,LoongArch,Sparc] Migrate to new encodeInstruction that uses SmallVectorImpl<char>. NFC

The LoongArch ELF psABI document has changed location and versioning
scheme; this revision is v2.10 in the old scheme. Notably this revision
brings initial capability of linker relaxation to LoongArch.

This is the following of https://reviews.llvm.org/D135550, which is
discussed in
https://discourse.llvm.org/t/rfc-unify-memory-effect-attributes/65579.
In my imagination, we could fix the issue fundamentally after we
introduces new memory kind thread id. But I am not very sure if we can
fix the issue fundamentally in time.

Besides that, I think the correctness is the most important. So it
should not be bad to land this given it is innocent.

In https://reviews.llvm.org/D147812 I created
`BalancedPartitioningTest.cpp` and inadvertently drastically increased the
number of files needed to compile `SupportTests`. Instead lets move the
`BPFunctionNode` test to `unittests/ProfileData` so we can remove the
extra dependency.

It's possible that both multiplicands are being negated. This won't
change the opcode, but we can delete the two negates. Allow this
case to get through negateFMAOpcode.

I think D152260 will also fix this test case, but in the future
it may be possible for an fneg to appear after we've already converted
to RISCVISD opcodes in which case D152260 won't help.

This seems to cause hwasan tests to run in environments it didn't run in before.

Fix debug printing, making it easier to compare two debug logs side by side:
- `BinaryFunction::addRelocation`: print function name instead of `this` ptr,
- `DataAggregator::doTrace`: remove duplicated function name.

64666d46 incorrectly removed REQUIRES.
2 RUN lines do need x86-registered-target.

Also introduce __builtin_ldexpf16.

AMDGPU has native instructions and target intrinsics for this, but
these really should be subject to legalization and generic
optimizations. This will enable legalization of f16->f32 on targets
without f16 support.

Implement a somewhat horrible inline expansion for targets without
libcall support. This could be better if we could introduce control
flow (GlobalISel version not yet implemented). Support for strictfp
legalization is less complete but works for the simple cases.

This simplifies the usage of `__less` by making the class not depend on the types compared, but instead the `operator()`. We can't remove the template completely because we explicitly instantiate `std::__sort` with `__less<T>`.

Parametrize SampleProfileInference and SampleProfileLoaderBaseImpl by function
type (Function/MachineFunction) instead of block type
(BasicBlock/MachineBasicBlock). Move out specializations to appropriate
locations.

This change makes it possible to use GraphTraits instead of a custom TypeMap and
make SampleProfileInference not dependent on LLVM types, paving the way for
generalizing SampleProfileInference interfaces to BOLT IR types
(BinaryFunction/BinaryBasicBlock) in stale profile matching (D144500).
