22afb55fb5 Add the beginning of a Debug Info guide for SIL pass authors. 
This document describes how debug info works at the SIL level and how to
correctly update debug info in SIL optimization passes. This document is
inspired by its LLVM analog, "How to Update Debug Info: A Guide for LLVM Pass
Authors", which can be found at https://llvm.org/docs/HowToUpdateDebugInfo.html

270be443b2 ASTMangler: Support for pack conformances 
The names of the private witness table accessor thunks we generate for
an opaque return type mangle the concrete conformance of the underlying
type.

If a conformance requirement of the opaque return type was witnessed by
a conditional conformance of a variadic generic type, we would crash
because of an unimplemented case in the mangler.

Fixes rdar://problem/125668798.

757ebe2979 Future-proof the mangling of invertible protocols 
Invertible protocols are currently always mangled with `Ri`, followed by
a single letter for each invertible protocol (e.g., `c` and `e` for
`Copyable` and `Escapable`, respectively), followed by the generic
parameter index. However, this requires that we extend the mangling
for any future invertible protocols, which mean they won't be
backward compatible.

Replace this mangling with one that mangles the bit # for the
invertible protocol, e.g., `Ri_` (followed by the generic parameter
index) is bit 0, which is `Copyable`. `Ri0_` (then generic parameter
index) is bit 1, which is `Escapable`. This allows us to round-trip
through mangled names for any invertible protocol, without any
knowledge of what the invertible protocol is, providing forward
compatibility. The same forward compatibility is present in all
metadata and the runtime, allowing us to add more invertible
protocols in the future without updating any of them, and also
allowing backward compatibility.

Only the demangling to human-readable strings maps the bit numbers
back to their names, and there's a fallback printing with just the bit
number when appropriate.

Also generalize the mangling a bit to allow for mangling of invertible
requirements on associated types, e.g., `S.Sequence: ~Copyable`. This
is currently unsupported by the compiler or runtime, but that may
change, and it was easy enough to finish off the mangling work for it.

* Workaround LLVM coroutine codegen problem: it assumes that unwind path never returns.
This is not true to Swift coroutines as unwind path should end with error result.
