N4100 states that an error shall be reported if
`!exists(p) || !is_directory(p)`. We were missing the first half of the
conditional. Invert the error and normal code paths to make the code
easier to follow.

Summary: This avoid the need to duplicate all pattern and actually end up exposing some opportunity to optimize existing pattern that did not exists in both directions on an existing test case.

Summary:
This patch tablegen-erates the ARM register bank information so that the
static tables added in D27807 no longer need to be maintained.

It is sufficient to skip emission of these arguments as we have nothing
to actually pass through the function call.
The AVR-GCC reference has nothing to say about zero-sized arguments,
presumably because C/C++ doesn't support them. This means we don't have
to worry about ABI differences.

don't create a platform.linux setting category, as it contains no
actual settings, and I don't forsee adding any soon. Also remove some
unused includes while I'm in there.

Summary:
Per discussion in D28616, having two ways two request logging (log
enable lldb XXX verbose && log enable -v lldb XXX) is confusing. This
removes the first option and standardizes all code to use the second
one.
I've added a LLDB_LOGV macro as a shorthand for if(log &&
log->GetVerbose()) and switched most of the affected log statements to
use that (I've only left a couple of cases that were doing complex
computations in an if(log) block).

It is my opinion that libc++ should never use `<cassert>`, including in the `dylib`.
This patch remove all uses of `assert` from within libc++ and replaces most of them with `_LIBCPP_ASSERT` instead.
Additionally this patch turn `LIBCXX_ENABLE_ASSERTIONS` off by default,
because the standard library should not be aborting user programs unless explicitly asked to.

Building lld is enabled by default, but it can be disabled using the
-no-lld option.

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.
