[lldb-dap] Move targetId and debuggerId into a session property (#175930)
This makes it clear the fields required for attaching to an existing
debug session.
It also makes it easier to check mutually exclusive fields required to
attach.

[JITLink][CompactUnwind] Explicitly enumerate mergeable encodings. NFCI. (#176317)
Updates CompactUnwindTraits_MachO_arm64 and
CompactUnwindTraits_MachO_x86_64 encodingCanBeMerged methods to use
switch statements that clearly list mergeable encodings, and have a
default "false" case.
Since the new scheme explicitly covers DWARF modes (always
non-mergeable), this patch removes the separate DWARF mode check from
mergeRecords in CompactUnwindSupport.h.
[RISCV] Use NoV0 register classes for masked `VPseudoBinaryM` (#175706)
There are two constraints:
1. The same register can't have two EEWs. `V0` is already the mask
register, so other register source operands can't be `V0`.
2. The destination and source registers can't overlap. We have added
`@earlyclobber` constraint so we won' allocate `V0` to destination.
[BOLT][BTI] Patch LLD-generated PLTs to contain BTI landing pad
This patch adds the patchPLTEntryForBTI to enable patching PLT entries
generated by LLD.
Context:
To keep BTI consistent, targets of stubs inserted in LongJmp need to be
patched. As PLTs are not optimized and emitted by BOLT, this patch adds
a helper for patching them in the original location.
For PLTs generated by LLD, this is safe as LLD inserts extra nops to
PLTs which don't already contain a BTI.
PLT entry before patching:
adrp x16, Page(&(.got.plt[n]))
ldr x17, [x16, Offset(&(.got.plt[n]))]
add x16, x16, Offset(&(.got.plt[n]))

Update __init__.py to add Cygwin as a classifier
Add "Environment :: Cygwin (MS Windows)" as a classifier as some modules, such as mine, work on Windows but only via the Cygwin POSIX layer (www.cygwin.com)
[BOLT][BTI] Disassemble PLT entries when processing BTI binaries (#169663)
PLT entries are PseudoFunctions, and are not disassembled or emitted.
For BTI, we need to check the first MCInst of PLT entries, to see
if indirectly calling them is safe or not.
This patch disassembles PLTs for binaries using BTI, while not changing
the behaviour for binaries without BTI.
The PLTs are only disassembled, not emitted.
