[InstSimplify] delete shift-of-zero guard ops around funnel shifts
This is a problem seen in common rotate idioms as noted in:
https://bugs.llvm.org/show_bug.cgi?id=34924
Note that we are not canonicalizing standard IR (shifts and logic) to the intrinsics yet.
(Although I've written this before...) I think this is the last step before we enable
that transform. Ie, we could regress code by doing that transform without this
simplification in place.
In PR34924, I questioned whether this is a valid transform for target-independent IR,
but I convinced myself this is ok. If we're speculating a funnel shift by turning cmp+br
into select, then SimplifyCFG has already determined that the transform is justified.
It's possible that SimplifyCFG is not taking into account profile or other metadata,
but if that's true, then it's a bug independent of funnel shifts.
Also, we do have CGP code to restore a guard like this around an intrinsic if it can't
be lowered cheaply. But that isn't necessary for funnel shift because the default
expansion in SelectionDAGBuilder includes this same cmp+select.

Start adding the supporting code to perform out-of-process allocator
enumeration.
Summary:
This patch introduces the local portion (`LocalAddressSpaceView`) of the
`AddressSpaceView` abstraction and modifies the secondary allocator
so that the `ForEachChunk()` method (and its callees) would work in the
out-of-process case when `AddressSpaceView` is `RemoteAddressSpaceView`.
The `AddressSpaceView` abstraction simply maps pointers from a target
process to a pointer in the local process (via its `Load()` method). For
the local (in-process) case this is a no-op. For the remote
(out-of-process) case this is not a no-op. The implementation of the
out-of-process `RemoteAddressSpaceView` is not included in this patch
and will be introduced later.
This patch is considerably simpler than the `ObjectView` abstraction
used in previous patches but lacks the type safety and stricter memory
management of the `ObjectView` abstraction.
This patch does not introduce any tests because with
`LocalAddressSpaceView` it should be a non functional change and unit
tests already cover the secondary allocator. When
`RemoteAddressSpaceView` is landed tests will be added to ensure that it
functions as expected.

[RISCV] Introduce the RISCVMatInt::generateInstSeq helper
Logic to load 32-bit and 64-bit immediates is currently present in
RISCVAsmParser::emitLoadImm in order to support the li pseudoinstruction. With
the introduction of RV64 codegen, there is a greater benefit of sharing
immediate materialisation logic between the MC layer and codegen. The
generateInstSeq helper allows this by producing a vector of simple structs
representing the chosen instructions. This can then be consumed in the MC
layer to produce MCInsts or at instruction selection time to produce
appropriate SelectionDAG node. Sharing this logic means that both the li
pseudoinstruction and codegen can benefit from future optimisations, and
that this logic can be used for materialising constants during RV64 codegen.
This patch does contain a behaviour change: addi will now be produced on RV64
when no lui is necessary to materialise the constant. In that case addiw takes
x0 as the source register, so is semantically identical to addi.

[X86] Add some custom type legalization rules for truncate with -x86-experimental-vector-widening-legalization.
This avoids some nasty shuffles when we have avx512. It will also prevent using zmm truncate instructions when a ymm instruction that zeroes part of an xmm register will do. Also avoid using avx512 truncate instructions when the input is 128 bits or less. These instructions are 2 uops on skx so we can probably find a better single uop shuffle like pshufb.

Fix combining pragma __debug dump & parser_crash with -E
Previously these would be transformed into annotation tokens and the
preprocessor would then assume they were real tokens with source
locations and assert/UB.
Other pragmas that produce annotation tokens aren't a problem because
they aren't handled if the parser isn't hooked up - ParsePragma.cpp
registers those handlers & isn't run for pure preprocessing. So they're
treated as unknown pragmas & printed verbatim by the preprocessor.
Perhaps these pragmas should be treated the same way? But they got mixed
in with other __debug pragmas that do need to be handled during
preprocessing.
The third __debug pragma that produces an annotation token is 'captured'
- which had its own fix for this issue - by not inserting the annotation
token in the first place if it detected that it was in preprocessing
mode. I've removed that fix (from Lex/Pragma.cpp) in favor of the more
general one in Frontend/PrintPreprocessedOutput.cpp.

Add setting to require hardware breakpoints.
When debugging read-only memory we cannot use software breakpoint. We
already have support for hardware breakpoints and users can specify them
with `-H`. However, there's no option to force LLDB to use hardware
breakpoints internally, for example while stepping.
This patch adds a setting target.require-hardware-breakpoint that forces
LLDB to always use hardware breakpoints. Because hardware breakpoints
are a limited resource and can fail to resolve, this patch also extends
error handling in thread plans, where breakpoints are used for stepping.
