Formatting of chrono types in log messages was very clunky. This should
make it much nicer to use and give better output. For details of the

Summary:
This converts LLDB's logging to use llvm streams instead of
lldb_private::Stream and friends. The changes are mostly
straight-forward and amount to s/lldb_private::Stream/llvm::raw_ostream.
The part worth calling out is the rewrite of the StreamCallback class.
Previously this class contained a per-thread buffer of data written. I
assume this had something to do with it trying to make sure each log
line is delivered as a single event, instead of multiple (possibly
interleaved) events. However, this is no longer relevant as the Log
class already writes things to a temporary buffer and then delivers the
message as a single "write", so I have just removed the code in
question.

This change clarfies that we want to indeed use the original base address
when creating the ScopArrayInfo that corresponds to a given memory access.
This change prepares for https://reviews.llvm.org/D28518.
llvm-svn: 294734
This replaces the use of getOriginalAddrPtr, a value that is stored in
ScopArrayInfo and might at some point not be unique any more. However, the
access value is defined to be unique.
This change is an update on r294576, which only clarified that we need the
original memory access, but where we still remained dependent to have one base
pointer per scop.
This change removes unnecessary uses of MemoryAddress::getOriginalBaseAddr() in
preparation for https://reviews.llvm.org/D28518.

This recommits r294707 with additional fixes. The main difference is
libc++ now correctly builds without any ABI library.
exception.cpp is a bloody mess. It's full of confusing #ifdef branches for
each different ABI library we support, and it's getting unmaintainable.
This patch breaks down exception.cpp into multiple different header files,
roughly one per implementation. Additionally it moves the definitions of
exceptions in new.cpp into the correct implementation header.
This patch also removes an unmaintained libc++abi configuration.
This configuration may still be used by Apple internally but there
are no other possible users. If it turns out that Apple still uses
this configuration internally I will re-add it in a later commit.

Without any loops, we don't even bother to build the standard analyses
used by loop passes. Without these, we can't run loop analyses or
invalidate them properly. Unfortunately, we did these things in the
wrong order which would allow a loop analysis manager's proxy to be
built but then not have the standard analyses built. When we went to do
the invalidation in the proxy thing would fall apart. In the test case
provided, it would actually crash.
The fix is to carefully check for loops first, and to in fact build the
standard analyses before building the proxy. This allows it to
correctly trigger invalidation for those standard analyses.
An alternative might seem to be to look at whether there are any loops
when doing invalidation, but this doesn't work when during the loop
pipeline run we delete the last loop. I've even included that as a test
case. It is both simpler and more robust to defer building the proxy
until there are definitely the standard set of analyses and indeed
loops.
This bug was uncovered by enabling GlobalsAA in the pipeline.

Chandler mentioned at the last social that the need for BFI in the new pass manager was causing a slight hiccup for this pass. Given this code has been checked in, but off for over a year, it makes sense to just remove it for now.
Note that there's nothing wrong with the general idea - it's actually a quite good one - and once we have the infrastructure in place to implement this without the full recompuation on every loop, we absolutely should.

Summary:
With -debug, we aren't dumping the DAG after legalizing vector ops. In particular, on X86 with AVX1 only, we don't dump the DAG after we split 256-bit integer ops into pairs of 128-bit ADDs since this occurs during vector legalization.
I'm only dumping if the legalize vector ops changes something since we don't print anything during legalize vector ops. So this dump shows up right after the first type-legalization dump happens. So if nothing changed this second dump is unnecessary.
Having said that though, I think we should probably fix legalize vector ops to log what its doing.

Instead of emitting the matcher code directly, return the rule matcher
and the skip reason as an Expected<RuleMatcher>.
This will let us record all matchers and process them before emission.
It's a somewhat unconventional use of Error, but it's nicer than, say,
std::pair, because of the bool conversions.
