[SLP][NFC] Update partial_vec_invalid_cost() test to avoid breakage by #181731 (#181914)
This test creates an invalid vector cost, but #181731 allows
transforming of lshr 0, 0 -> add 0, 0 which in turn allows costing of
the following TreeEntry since is will be considered as 4 `ADD`
operations.
```
%lshr.1 = lshr i96 0, 0
%lshr.2 = lshr i96 0, 0
%add.0 = add i96 0, 0
%add.1 = add i96 0, 0
```
This commit adjusts the operands to ensure an invalid cost is still
generated after #181731.
This test was originally added in
4652ec0e291ca4ba4ddef3fd59b202646e9a6694.
vfs_mount.c: Don't call VFS_MOUNT() if only exports are being updated
PR#293198 reports a hang within ZFS when exports
are being updated concurrently with a VOP_SETEXTATTR().
The hang appears to be caused by mishandling of the
z_teardown_lock, but fixing handling of this lock appears
to be a major effort. Since the hang occurs when
VFS_MOUNT() acquires a write/exclusive z_teardown_lock,
which rarely occurs, except when exports are being updated,
this patch avoids the VFS_MOUNT() call for this case.
Avoiding a VFS_MOUNT() call fixes the hang for the case
reported by PR#293198 and is also an optimization.
As such, this patch avoids the VFS_MOUNT() call when only exports
are being updated similar to what was already being done
within vnet prisons.

t_fpclassify: Show the floating-point bits more carefully.
Use formatbits(&f) rather than formatbits(f). This serves two
purposes:
1. Type-checking.
Can't accidentally pass a double where a float is needed -- a bug
that previously appeared a few times in this code.
2. Reducing the chance that the data will pass through floating-point
load/store instructions on x87.
Floating-point load of binary32 (float) or binary64 (double)
converts to x87 80-bit extended precision format internally, which
preserves all floating-point _numbers_ and _infinities_ but has
the side effect of changing signalling NaN to quiet NaN (and
raising FE_INVALID). This means that signalling NaNs were getting
wrongly printed _as if_ they were quiet NaNs, which is frustrating

[lldb][windows] release the ConPTY instead of copying its reference (#181811)
When running multiple targets in lldb, the `ProcessLaunchInfo` instance
gets re-used. This is a problem for the ConPTY instance which is owned
by `launch_info` because, when creating a second target, we close and
reopen the `m_pty` of the first target.
This patch replaces the `GetPTYSP` method with `ReleasePTY`, which moves
the `std::shared_ptr` out of `launch_info` instead of creating a new
`std::shared_ptr`. The `m_pty` instance is moved into the target's
process. This way, each target's `Process` instance owns its PTY
instance and is responsible for closing it.

[SPIRV] Prevent BB start emission for service functions (#178776)

BB start emission for such cases.
[lldb-dap] Validate utf8 protocol messages. (#181261)
I ran into this while debugging a different issue, but when we calcualte
the 'value' field of a variable we were not ensuring the contents were
valid utf8. If assertions are enabled then llvm::json::Value will assert
that the string contains invalid utf8.
To address this I added a wrapper type (`lldb_dap::protocol::String`)
that can be used as a thin wrapper around `std::string` to ensure a
field contains valid utf8. This is now used throughout the
`lldb_dap::protocol::*` types.
