[LLDB] [NFC] Typo fix in usage text for "type filter" command

When you invoke "help type filter" the resulting help shows:

Syntax: type synthetic [<sub-command-options>]

This patch fixes the help so it says "type filter" instead of "type synthetic".

[lldb][NFC] clang-format CPlusPlusLanguage.cpp

[mlir][linalg][bufferize] Bufferize using PostOrder traversal

This is required for bufferization of scf::IfOp, which is added in a subsequent commit.

Some ops (scf::ForOp, TiledLoopOp) require PreOrder traversal to make sure that bbArgs are mapped before bufferizing the loop body.

[mlir][linalg][bufferize][NFC] Check return value of getResultBuffer

In a subsequent commit, getResultBuffer can return a "null" Value. This is the case when the returned buffer from an scf.if is not unique.

This commit is in preparation for scf.if support to keep the next commit smaller.

[MLIR][OpenMP] Add support for ordered construct

This patch supports the ordered construct in OpenMP dialect following
Section 2.19.9 of the OpenMP 5.1 standard. Also lowering to LLVM IR
using OpenMP IRBduiler. Lowering to LLVM IR for ordered simd directive
is not supported yet since LLVM optimization passes do not support it
for now.

[lldb] [Host] Add setters for common teletype properties to Terminal

Add setters for common teletype properties to the Terminal class:

- SetRaw() to enable common raw mode options

- SetBaudRate() to set the baud rate

- SetStopBits() to select the number of stop bits

- SetParity() to control parity bit in the output

- SetHardwareControlFlow() to enable or disable hardware control flow
  (if supported)

[SVE][Analysis] Tune the cost model according to the tune-cpu attribute

This patch introduces a new function:

  AArch64Subtarget::getVScaleForTuning

that returns a value for vscale that can be used for tuning the cost
model when using scalable vectors. The VScaleForTuning option in
AArch64Subtarget is initialised according to the following rules:

1. If the user has specified the CPU to tune for we use that, else
2. If the target CPU was specified we use that, else
3. The tuning is set to "generic".

For CPUs of type "generic" I have assumed that vscale=2.

New tests added here:

  Analysis/CostModel/AArch64/sve-gather.ll
  Analysis/CostModel/AArch64/sve-scatter.ll
  Transforms/LoopVectorize/AArch64/sve-strict-fadd-cost.ll

[mlir][linalg][bufferize][NFC] Change findValueInReverseUseDefChain signature

This commit is in preparation for scf.if support.

* `condition` in findValueInReverseUseDefChain takes a Value instead of OpOperand*.
* Return a SetVector<Value> instead of a single Value. This SetVector always contains exactly one Value at the moment.

[NARY-REASSOCIATE][NFC] Simplify min/max handling

In order to explore different variants of reassociation current implementation uses "swap in a loop" approach. Unfortunately, the implementation is more complicated than it could be. This is an attempt to streamline the code. New approach is to extract core functionality into a helper function and call it explicitly as many times as required.

[lldb] Add serial:// protocol for connecting to serial port

Add a new serial:// protocol along with SerialPort that provides a new
API to open serial ports.  The URL consists of serial device path
followed by URL-style options, e.g.:

    serial:///dev/ttyS0?baud=115200&parity=even

If no options are provided, the serial port is only set to raw mode
and the other attributes remain unchanged.  Attributes provided via
options are modified to the specified values.  Upon closing the serial
port, its original attributes are restored.

[lldb] [unittest] Disable SetParity() tests on Linux entirely

Attempting to enable PARENB causes tcsetattr() to fail on the Debian
