Add LLDB website and documentation in reStructuredText for Sphinx
The current LLDB website is written in HTML which is hard to maintain.
We have quite a bit of HTML code checked in which can make it hard to
differentiate between documentation written by us and documentation
generated by a tool.
In line with the other LLVM projects, I propose generating the
documentation with Sphix. I think text/rst files provide a lower barrier
for new or casual contributors to fix or update.
This patch adds a copy of the LLDB website and documentation in
reStructuredText. It also adds a new ninja target `docs-lldb-html` when
-DLLVM_ENABLE_SPHINX:BOOL is enabled.
This is the first step in having the website and documentation being
generated from the repository, rather than having the output checked-in
under the www folder. During the hopefully short transition period,
please also update the reStructuredText files when modifying the
website.

[WebAssembly] Exception handling: Switch to the new proposal
Summary:
This switches the EH implementation to the new proposal:
https://github.com/WebAssembly/exception-handling/blob/master/proposals/Exceptions.md
(The previous proposal was
https://github.com/WebAssembly/exception-handling/blob/master/proposals/old/Exceptions.md)
- Instruction changes
- Now we have one single `catch` instruction that returns a except_ref
value
- `throw` now can take variable number of operations
- `rethrow` does not have 'depth' argument anymore
- `br_on_exn` queries an except_ref to see if it matches the tag and
branches to the given label if true.
- `extract_exception` is a pseudo instruction that simulates popping
values from wasm stack. This is to make `br_on_exn`, a very special
instruction, work: `br_on_exn` puts values onto the stack only if it
is taken, and the # of values can vay depending on the tag.
- Now there's only one `catch` per `try`, this patch removes all special
handling for terminate pad with a call to `__clang_call_terminate`.
Before it was the only case there are two catch clauses (a normal
`catch` and `catch_all` per `try`).
- Make `rethrow` act as a terminator like `throw`. This splits BB after
`rethrow` in WasmEHPrepare, and deletes an unnecessary `unreachable`
after `rethrow` in LateEHPrepare.
- Now we stop at all catchpads (because we add wasm `catch` instruction
that catches all exceptions), this creates new
`findWasmUnwindDestinations` function in SelectionDAGBuilder.
- Now we use `br_on_exn` instrution to figure out if an except_ref
matches the current tag or not, LateEHPrepare generates this sequence
for catch pads:
```
catch
block i32
br_on_exn $__cpp_exception
end_block
extract_exception
```
- Branch analysis for `br_on_exn` in WebAssemblyInstrInfo
- Other various misc. changes to switch to the new proposal.

lld/coff: Implement some support for the comdat selection field
LLD used to handle comdats as if the selection field was always set to
IMAGE_COMDAT_SELECT_ANY. This means for obj files produced by `cl /Gy`, LLD
would never report a duplicate symbol error.
This change:
- adds validation for the Selection field (should make no difference in
practice for compiler-generated obj inputs)
- rejects comdats that have different Selection fields in different obj files
(likewise). This is a bit more strict but also more self-consistent thank
link.exe (see comment in code)
- implements handling for all the selection kinds
In practice, compilers only generate comdats with
IMAGE_COMDAT_SELECT_NODUPLICATES (LLD now produces duplicate symbol errors for
these), IMAGE_COMDAT_SELECT_ANY (no behavior change), and
IMAGE_COMDAT_SELECT_LARGEST (for RTTI data; here LLD should no longer create
broken executables when linking some TUs with RTTI enabled and some with it
disabled – but see below).
The implementation of `IMAGE_COMDAT_SELECT_LARGEST` is incomplete: If one
SELECT_LARGEST comdat replaces an earlier one, the comdat symbol is replaced
correctly, but the old section stays loaded and if /opt:ref is disabled (via
/opt:noref or /debug) it's still written to the output. That's not ideal, but
better than the current treatment of just picking any one of those comdats. I
hope to fix this better later.
