Summary:
I discovered accidentally that the operator== for TargetOptions
is stale - it is missing many fields that have been added over
the recent years. It isn't used, so remove it. Ditto for the
comparator in MCTargetOptions, which doesn't seem stale yet but is
unused.

The checker currently warns on copying, moving, or calling methods on an object
that was recently std::move'd from. It understands a set of "state reset"
methods that bring a moved-from object back to a well-specified state.

attributes.
These patches don't work because we can't currently access the parameter
information in a reliable way when building attributes. I thought this
would be relatively straightforward to fix, but it seems not to be the
case. Fixing this will requrie a substantial re-plumbing of machinery to
allow attributes to be handled in this location, and several other fixes
to the attribute machinery should probably be made at the same time. All
of this will make the patch .... substantially more complicated.
Reverting for now as there are active miscompiles caused by the current
version.

was formatted into a string inside an assert() expression.
Which is elided when lldb is built with asserts disabled;
the result is that all expressions will fail when debugging
programs using the objective-c v1 runtime.

The patch rL298481 was reverted due to crash on clang-with-lto-ubuntu build.
The reason of the crash was type mismatch between either a or b and RHS in the following situation:
LHS = sext(a +nsw b) > RHS.
This is quite rare, but still possible situation. Normally we need to cast all {a, b, RHS} to their widest type.
But we try to avoid creation of new SCEV that are not constants to avoid initiating recursive analysis that
can take a lot of time and/or cache a bad value for iterations number. To deal with this, in this patch we
reject this case and will not try to analyze it if the type of sum doesn't match with the type of RHS. In this
situation we don't need to create any non-constant SCEVs.
This patch also adds an assertion to the method IsProvedViaContext so that we could fail on it and not
go further into range analysis etc (because in some situations these analyzes succeed even when the passed
arguments have wrong types, what should not normally happen).
The patch also contains a fix for a problem with too narrow scope of the analysis caused by wrong
usage of predicates in recursive invocations.

This change allows cross-compiling compiler-rt builtins for
multiple targets as part of runtimes on Darwin. This functionality
is already supported on other platforms.

r298178 capitalized the fields in `ArgListEntry`. All the official
targets were updated accordingly, but as an experimental target AVR
was missed.

This change fixes a crash on initialization of a reference from ({}) during
template instantiation and incidentally improves diagnostics.
This reverts a prior attempt to handle this in r286721. Instead, we teach the
initialization code that initialization cannot be performed if a source type
is required and the initializer is an initializer list (which is not an
expression and does not have a type), and likewise for function-style cast
expressions.

The original code is a big `if` and `else` which ends with `continue`
like this:
if (cond) {
...
// fall through
} else {
...
continue;
}
This patch rewrites it with the following.
if (!cond) {
...
continue;
}

Summary:
Now that XRay doesn't require a runtime dependency on a C++ standard
library, we remove that dependency from the clang linker flags.

This prevents crashes when attempting to instrument functions containing
C++ try.
Sanitizer coverage will still fail at runtime when an exception is
thrown through a sancov instrumented function, but that seems marginally
better than what we have now. The full solution is to color the blocks
in LLVM IR and only instrument blocks that have an unambiguous color,
using the appropriate token.

Summary:
For the following CFG:
A->B
B->C
A->C
If there is another edge B->D, then ABC should not be considered as triangle.

Summary: In DeadArgumentElimination, the call instructions will be replaced. We also need to set the prof weights so that function inlining can find the correct profile.

Library functions can have specific semantics that affect the behavior of
certain passes. DSE, for instance, gives special treatment to malloc-ed pointers
but not to pointers returned from an equivalently typed (but differently named)
function.
MetaRenamer ought not to alter program semantics, so library functions must
remain untouched.
