Support: Add closing namespace comment in raw_ostream_test.cpp, NFC

The closing namespace comment prevents clang-format from dropping a
blank line after the final test. Also add in a blank line (which
simplifies merging/rebasing/etc. WIP patches).

[clangd] Support `#pragma mark` in the outline

Xcode uses `#pragma mark -` to draw a divider in the outline view
and `#pragma mark Note` to add `Note` in the outline view. For more
information, see

Since the LSP spec doesn't contain dividers for the symbol outline,
instead we treat `#pragma mark -` as a group with children - the
decls that come after it, implicitly terminating when the symbol's
parent ends.

The following code:

@implementation MyClass

- (id)init {}

- (int)foo;

Would give an outline like

        > Overrides
                    > init
        > Public Accessors
                    > foo

[RISCV] Add more tests for (and (shl x, C2), C1) that can be improved by using a pair of shifts. NFC

These tests have C1 as a shifted mask having no leading zeros and

[OpenMP] Fix data-race in new device RTL

This patch fixes a data-race observed when using the new device runtime
library. The Internal control variable for the parallel level is read in
the `__kmpc_parallel_51` function while it could potentially be written
by other threads. This causes data corruption and will cause
nondetermistic behaviour in the runtime. This patch fixes this by adding
an explicit synchronization before the region starts.

[lldb] Handle malformed qfThreadInfo reply

If the remote gdbserver's qfThreadInfo reply has a trailing comma,
GDBRemoteCommunicationClient::GetCurrentProcessAndThreadIDs will return
an empty vector of thread ids. This will cause lldb to recurse through
three functions trying to get the list of threads, until it blows its
stack and crashes.

A trailing comma is a malformed response, but it shouldn't cause lldb to
crash. This patch will return the tids received before the malformed

[AMDGPU] Propagate defining src reg for AGPR to AGPR Copys

On targets that do not support AGPR to AGPR copying directly, try to find the
defining accvgpr_write and propagate its source vgpr register to the copies
before register allocation so the source vgpr register does not get clobbered.

The postrapseudos pass also attempt to propagate the defining accvgpr_write but
if the register to propagate is clobbered, it will give up and create new
temporary vgpr registers instead.
