[lldb][Windows] Fix ECHO_TO_FILE/ECHO_APPEND_FILE (#202612)
The Windows recipes for these macros were `printf "%s\n" $(1)`. The
callers wrap content in single quotes (for the POSIX printf), but the
test recipes run under `cmd.exe` on Windows, which keeps the single
quotes literal and word-splits on spaces, and the bundled `printf`
additionally mangles backslashes and spaces. The result is garbage
generated files (e.g. a modulemap whose first line is `'module`, or a
truncated SDK path from a "Program Files" directory).
Write the file with cmd's `echo` after stripping the callers' single
quotes. `echo` runs in the recipe shell, so unlike GNU make's `$(file
...)` it still works after a preceding `MKDIR_P` in the same recipe.

interfaces: parse ifconfig output despite exit error in legacy_interfaces_details()
Move stderr to /dev/null and always read stdout. It improves intermittent
issues with ifconfig that will return data but "fail" with a non-zero return
code.

[LV] Add initial costs for VPInstructionWithType::computeCost (#198291)
I noticed this was previously always returning a cost of 0
due to fear of triggering the (now deleted) legacy/vplan
cost model assert. Since the assert has now been removed
this should be safe to implement properly. I haven't
filled in the costs for all types yet, since there is
currently no way to expose those code paths. I suspect
for things like VPInstruction::StepVector the recipe is
always in the vector preheader and we never ask for its
cost.
[LLD][ELF] Do not reuse thunks in OVERLAYs (#200415)
We cannot guarantee that a thunk in an OVERLAY will be in memory at the
same time as the caller if the caller is not in the same output section.
It is safe for a caller in an OVERLAY to reuse a thunk in a non-OVERLAY
section as we know that will be in memory. Thunks that are placed
before their target, are alternative entry points and can also be reused.
Resurrect the isThunkSectionCompatible function that was recently
removed as it served a similar purpose for thunks in different
partitions.
Potentially fixes #199966 which mentions a similar problem for sections
assigned to TCM (Tightly Coupled Memory). It should be possible to model
a TCM as an OVERLAY. If not then there may need to be a command-line
option to inhibit thunk sharing across output sections.
[orc-rt] Treat empty path as "process symbols" in NativeDylibManager. (#202905)
NativeDylibManager::load now handles an empty path by returning the
process's global lookup handle (RTLD_DEFAULT on POSIX) directly,
bypassing dlopen and the shutdown-time dlclose registration. This
matches the behavior of OrcTargetProcess's SimpleExecutorDylibManager.
[AMDGPU] Support Wave Reduction for i16 types - 1 (#194808)
Supported Ops: `min`, `umin`, `max`, `umax`.
16-bit wave reduce ops are promoted to 32-bit
operations before ISEL. From there they use the
existing implementations for 32-bit reductions.

[AMDGPU] Support Wave Reduction for i16 types - 3 (#194812)
Supported Ops: `and`, `or`, `xor`.
Supports only the iterative stratergy, DPP is yet
to be supported.
Supports only Fake-16 versions of the lowering.
True-16 support is yet to be added.

[AMDGPU][InsertWaitCnts] Move HWEvent analysis code
Building up on the previous RFC, if it is accepted:
Move the code that maps a MachineInstr to HWEventSet to a separate file.
This should be NFC.
