The libc++ data formatter for `std::shared_ptr` allows any namespace, but the test asserts that it must be the default `__1` namespace. Relax the regex to allow anything that looks like `__.*` (although we use `__[^:]*` so we don't match arbitrarily long text).

As strange as it seems to our files-are-strings view of the world, some editors
that treat files as arrays of lines can get confused about whether the last line
has a newline or not.

The consequences of failing to handle a bad incremental update are catastrophic.
If an update would be valid except for a missing newline at end of file, pretend
one exists.

Some headers in LLDB work only when considered as textual inclusion, but not if one attempts to use them on their own or with a different context.

- python-typemaps.h: uses Python definitions without using "Python.h".
- RISCVCInstructions.h uses RISC-V register enums without including the enums header.
- RISCVInstructions.h includes EmulateInstructionRISCV.h, but is unnecessary since we forward-declare EmulateInstructionRISCV anyway. Including the header is problematic because EmulateInstructionRISCV.h uses DecodeResult which isn't defined until later in RISCVInstructions.h.

This makes LLDB build cleanly with the "parse_headers" feature [1]. I'm not sure what the analagous CMake option is.

Currently, the import of LLVMIR fails if the program contains debug
intrinsics. The revision adds support to import debug intrinsics that
have no debug expression attached and drops all debug intrinsics with a
non-empty debug expression. It also moves the existing debug intrinsics
into the "intr" namespace by deriving from LLVM_IntrOp.

Previously, we just used the platform name. This worked mostly OK, but
it required adding special handling for any unusual (and potentially
downstream) platform plugins, as evidenced by the hardcoding of the
qemu-user platform.

The current implementation was added in
D121605/21c5bb0a, which this essentially
reverts and goes back to the previous method of retrieving the platform
name from the platform triple (the "OS" field).

The motivation for D121605 was the ability to retrieve the process
without constructing an SBDebugger object (which would be necessary in a
world where SBPlatforms are managed by SBDebuggers). However, this world
did not arrive (mainly due to other commitments on my part), and I now
think that if we do want to go in that direction, that we should just
create a dummy/empty SBDebugger object for holding the initial
SBPlatform.

One benefit of D121605 was the unification of getPlatform and
getHostPlatform code paths, and I preserve that benefit by unifying them
in the other direction -- using the host SBPlatform for getHostPlatform.

In revision B.q and before of the Armv8-M architecture reference
manual, the vector/scalar forms of the `vmla` and `vmlas` instructions
came in signed and unsigned integer forms, such as `vmla.s8 q0,q1,r2`
or `vmlas.u32 q3,q4,r5`.

Revision B.r has changed this. There are no longer signed and unsigned
versions of these instructions, since they were functionally identical
anyway. Now there is just `vmla.i8` (or `i16` or `i32`, and similarly
for `vmlas`). Bit 28 of the instruction encoding, which was previously
0 for signed or 1 for unsigned, is now expected to be 0 always.

This change updates LLVM to the new version of the architecture. The
obsoleted encodings for unsigned integers are now decoding errors, and
only the still-valid encoding is ever emitted. This shouldn't break
any existing assembly code, because the old signed and unsigned
versions of the mnemonic are still accepted by the assembler (which is
standard practice anyway for all signedness-agnostic MVE integer
instructions).

VectorToSCF conversion and enables the lowering of permutation maps
