Improve 'tail' call marking in TRE. A bootstrap of clang goes from 375k calls marked tail in the IR to 470k, however this improvement does not carry into an improvement of the call/jmp ratio on x86. The most common pattern is a tail call + br to a block with nothing but a 'ret'.

The number of tail call to loop conversions remains the same (1618 by my count).

The new algorithm does a local scan over the use-def chains to identify local "alloca-derived" values, as well as points where the alloca could escape. Then, a visit over the CFG marks blocks as being before or after the allocas have escaped, and annotates the calls accordingly.

Build debug info for ObjC interface types at the end of the translation unit to ensure all ivars are included.

This takes a different approach than the
completedType/requiresCompleteType work which relies on AST callbacks to
upgrade the type declaration to a definition. Instead, just defer
constructing the definition to the end of the translation unit.

This works because the definition is never needed by other debug info
(so far as I know), whereas the definition of a struct may be needed by
other debug info before the end of the translation unit (such as
emitting the definition of a member function which must refer to that
member function's declaration).

If we had a callback for whenever an IVar was added to an ObjC interface
we could use that, and remove the need for the ObjCInterfaceCache, which
might be nice. (also would need a callback for when it was more than
just a declaration so we could get properties, etc).

A side benefit is that we also don't need the CompletedTypeCache
anymore. Just rely on the declaration-ness of a type to decide whether
its definition is yet to be emitted.

There's still the PR19562 memory leak, but this should hopefully make
that a bit easier to approach.

Simplify replacement map by avoiding duplicate values and ensuring the values it does contain are necessary.

Items were being redundantly added to the replacement map (both when the
declaration was created, and then again when its definition was
constructed) which caused extra handling to be required when walking the
map (as elements may've already been replaced due to prior entries). By
avoiding adding the duplicates, the checks in the replacement handling
can be replaced with assertions.

Currently, users get error messages about RTTI descriptor mangling with
no useful source location.  This addresses that.

Another approach would be to disable C++ exceptions by default in the
driver when using the Microsoft C++ ABI.  However, this makes it
impossible to parse system headers that use exception handling
constructs.  By delaying the error to IRgen, we can figure out if we
actually need to emit code for this construct.  Additionally, users who
are only interested in building refactoring tools on Windows still get a
correct AST without having to add flags.  Finally, this is consistent
with what we do for SEH.

Pushed gdbremote protocol sequence expectations into a separate
class and defer matching of llgs/debugserver output to the
sequence entry.  Pre-step to adding regex matching and
grouped content collecting.

No longer require anything before the read/send packet
portion of slurped-up log lines used for setting up
gdb remote test sequences.  Several packet logging options
produce a wide range of content before the read/send packet.

Added helpers to TestLldbGdbServer to clean up test setup
and test expectations matching.
