Visible definitions for basic_string::assign are sometimes emitted in
the dylib depending on the version of LLVM used to compile libc++.
This can cause the check-cxx-abilist target to fail.
This patch attempts marks the basic_string::assign templates as inline
to prevent this. That way the export list is consistent across LLVM
versions.

This function has been extracted from the upcoming DeLICM patch
(https://reviews.llvm.org/D24716).
In contrast to computeReachingWrite and computeArrayUnused,
convertZoneToTimepoints implies a format for zones (ranges between timepoints).
Zones at the moment are unique to DeLICM, but convertZoneToTimepoints makes most
sense in conjunction with the previous two functions.

This was originally introduced in r278321 to work around correctness
problems in the ExecutionDepsFix pass; Probably also to keep the
performance benefits of breaking the false dependencies which of course
also affect undef operands.
ExecutionDepsFix has been improved here recently (see for example
r278321) so we should not need this exception any longer.

Move a check for blocks that are not candidates for tail duplication up before
the logging. Reduces logging noise. No non-logging changes intended.

Anything that needs to be passed to AnalyzeBranch unfortunately can't be const,
or more would be const. Added const_iterator to BlockChain to allow
BlockChain to be const when we don't expect to change it.

This lets us split out PatternToMatch from the top-level RuleMatcher,
where it doesn't really belong. That, in turn, lets us eventually
generate RuleMatchers from non-SelectionDAG sources.

Summary:
The current version of LLDB installs six.py into global python library directory. This approach produces conflicts downstream with distribution's py-six copy.
Introduce new configure option LLDB_USE_SYSTEM_SIX (disabled by default). Once specified as TRUE, six.py won't be installed to Python's directory.
Add new option in finishSwigWrapperClasses.py, namely --useSystemSix.

An assert occurs when calling SlotIndexes::getInstructionIndex with
a DBG_VALUE instruction because the function expects an instruction
with a slot index. However, there is no slot index for a DBG_VALUE
instruction.

This patch is based on the llvm-dev discussion here:
http://lists.llvm.org/pipermail/llvm-dev/2017-January/109631.html
Folding to i1 should always be desirable because that's better for value tracking
and we have special folds for i1 types.
I checked for other users of shouldChangeType() where this might have an effect,
but we already handle the i1 case differently than other types in all of those cases.
Side note: the default datalayout includes i1, so it seems we only find this gap in
shouldChangeType + phi folding for the case when there is (1) an explicit datalayout
without i1, (2) casting to i1 from a legal type, and (3) a phi with exactly 2 incoming
casted operands (as Björn mentioned).

While there is nothing to do at link time to get pthreads support on
darwin, specifying the argument is fine and we should not warn about
unused arguments.

Summary: As per title. I ran into that limitation of the API doing some other work, so I though that'd be a nice addition.

Summary:
The assumption __sanitizer_get_heap_size() == 0 (introduced in D29341) at the
start of a program appears to be incorrect on some ARM machines
(SizeClassAllocator32).
This should fix the test while I investigate the issue.
