Tie the Verifier class to a Module; NFCI
Summary:
This commit changes the Verifier class to accept a Module via the
constructor to make it obvious that a specific instance of the class is
only intended to work with a specific module. The `updateModule` setter
(despite being private) was making this fact less transparent.
There are fields in the `Verifier` class like `DeoptimizeDeclarations`
and `GlobalValueVisited` which are module specific, so a given
Verifier instance will not in fact work across multiple modules today.
This change just makes that more obvious.
The motivation is to make it easy to get to the datalayout of the
module unambiguously. That is required to verify that `inttoptr` and
`ptrtoint` constant expressions are well typed in the face of
non-integral pointer types.

libc++: test lock-free atomic alignment
Summary:
libc++ implements std::atomic<_Tp> using __atomic_base<_Tp> with
`mutable _Atomic(_Tp) __a_`. That member must be suitably aligned on
relevant ISAs for instructions such as cmpxchg to work properly, but
this alignment isn't checked anywhere. __atomic_base's implementation
relies on _Atomic doing "the right thing" since it's under the
compiler's control, and only the compiler knows about lock-freedom and
instruction generation. This test makes sure that the compiler isn't
breaking libc++'s expectations.
I'm looking at a few odd things in the C++ standard, and will have a few
other fixes around this area in the future.
This requires building with `-DLIBCXX_HAS_ATOMIC_LIB=True`, the test
marks the dependency as REQUIRES and won't be run without.

[Hexagon] Check for offset overflow when reserving scavenging slots
Scavenging slots were only reserved when pseudo-instruction expansion in
frame lowering created new virtual registers. It is possible to still
need a scavenging slot even if no virtual registers were created, in cases
where the stack is large enough to overflow instruction offsets.

Make RecursiveASTVisitor visit lambda capture initialization expressions
Summary:
Lambda capture initializations are part of the explicit source code and
therefore should be visited by default but, so far, RecursiveASTVisitor does not
visit them.
This appears to be an oversight. Because the lambda body needs custom handling
(calling TraverseLambdaBody()), the DEF_TRAVERSE_STMT for LambdaExpr sets
ShouldVisitChildren to false but then neglects to visit the lambda capture
initializations. This patch adds code to visit the expressions associated with
lambda capture initializations.

[SimplifyCFG] Range reduce switches
If a switch is sparse and all the cases (once sorted) are in arithmetic progression, we can extract the common factor out of the switch and create a dense switch. For example:
switch (i) {
case 5: ...
case 9: ...
case 13: ...
case 17: ...
}
can become:
if ( (i - 5) % 4 ) goto default;
switch ((i - 5) / 4) {
case 0: ...
case 1: ...
case 2: ...
case 3: ...
}
or even better:
switch ( ROTR(i - 5, 2) {
case 0: ...
case 1: ...
case 2: ...
case 3: ...
}
The division and remainder operations could be costly so we only do this if the factor is a power of two, and emit a right-rotate instead of a divide/remainder sequence. Dense switches can be lowered significantly better than sparse switches and can even be transformed into lookup tables.

Fix - CodeExtractor : Inherit Target Dependent Attributes from the parent function.
When extracting a set of blocks make sure to inherit all of the target
dependent attributes to make sure that the function will be valid for
lowering. One example is the "target-features" attribute for x86, if the
extracted region has functionality that relies on a specific feature it
will fail to be lowered.
This also allows for extracted functions to be valid for inlining, at
least back into the parent function, as the target attributes are tested
when inlining for compatibility.
