Added a packet history object to the GDBRemoteCommunication class that is always remembering the last 512 packets that were sent/received. These packets get dumped if logging gets enabled, or when the new expr lldb::DumpProcessGDBRemotePacketHistory (void *process, const char *log_file_path) global function is called.

Fixed an issue that could occur when looking up functions inside of a namespace where if the NamespaceDecl hadn't been parsed yet, we would say a function wasn't in a namespace.

Also improved the logging that happens with "log enable dwarf lookups" is enabled to show when we find matches.

base-class subojects.

Incidentally, thinking about virtual bases makes it clear to me that
we're not appropriately computing the access to the virtual base's
member because we're not computing the best possible access to the
virtual base at all;  in fact, we're basically assuming it's public.
I'll file a separate PR about that.

Work around a deadlocking issue where "SBDebugger::MemoryPressureDetected ()" is being called and is causing a deadlock. We now just try and get the lock when trying to trim down the unique modules so we don't deadlock debugger GUI programs until we can find the root cause.

This patch restores TwoAddressInstructionPass's pre-r153892 behaviour when
rescheduling instructions in TryInstructionTransform. Hopefully this will fix
PR12493. To refix PR11861, lowering of INSERT_SUBREGS is deferred until after
the copy that unties the operands is emitted (this seems to be a more
appropriate fix for that issue anyway).

We currently want to look whether PWD is available - if PWD is available it will
get us the non-resolved current path, while fs::current_path will resolve
symlinks. The long term fix is to not rely on that behavior any more.

Specifically, using a an integer outside [0, 1] as a boolean constant seems to
be an easy mistake to make with things like "x == a || b" where the author
intended "x == a || x == b".

The bug caused by calling SkipUntil with three token kinds was also identified
by a VC diagnostic & reported by Francois Pichet as review feedback for my
commit r154163. I've included test cases to verify the error recovery that was
broken/poorly implemented due to this bug.

The other fix (lib/Sema/SemaExpr.cpp) seems like that code was never actually
reached in any of Clang's tests & is related to Objective C features I'm not
familiar with, so I've not been able to construct a test case for it. Perhaps
someone else can.

A couple of cases where we were accidentally creating constant conditions by
something like "x == a || b" instead of "x == a || x == b". In one case a
conditional & then unreachable was used - I transformed this into a direct
assert instead.
