  [NVPTX] Only run LowerUnreachable when necessary (#109868)

Before CUDA 12.3 `ptxas` did not recognize that the trap instruction
terminates a basic block. Instead, it would assume that control flow
continued to the next instruction. The next instruction could be in the
block that's lexically below it. This would lead to phantom CFG edges
being created within ptxas.

[NVPTX: Lower unreachable to exit to allow ptxas to accurately
reconstruct the
CFG.](https://github.com/llvm/llvm-project/commit/1ee4d880e8760256c606fe55b7af85a4f70d006d)
added the LowerUnreachable pass to NVPTX to work around this. Several
other WAR patches followed.

This bug in `ptxas` was fixed in CUDA 12.3 and is thus impossible to
encounter when targeting PTX ISA v8.3+

This commit reverts the WARs for the `ptxas` bug when targeting PTX ISA
v8.3+

  [Coroutines] Documentation for custom ABIs (#111781)

Update the llvm/docs/Coroutines.rst docs to include a full description
of Custom ABI objects. This documentation describes the how ABI objects
allow users (plugin libraries) to create custom ABI objects for their
needs.

  [lldb] Implement basic support for reverse-continue (#99736)

This commit only adds support for the
`SBProcess::ReverseContinue()` API. A user-accessible command for this
will follow in a later commit.

This feature depends on a gdbserver implementation (e.g. `rr`) providing
support for the `bc` and `bs` packets. `lldb-server` does not support
those packets, and there is no plan to change that. So, for testing
purposes, `lldbreverse.py` wraps `lldb-server` with a Python
implementation of *very limited* record-and-replay functionality for use
by *tests only*.

The majority of this PR is test infrastructure (about 700 of the 950
lines added).

  [NFC][sanitizer] Reopen '/proc/%d/task' instead of seek

NFC because I am not aware of any particular
issue from seek, but reopen looks less error prone.
