whose tests would never run with new pass manager. Similarly, we would

Reduce amount of work ODR hashing does.
When a FunctionProtoType is in the original type in a DecayedType, the decayed
type is a PointerType which points back the original FunctionProtoType. The
visitor for ODRHashing will attempt to process both Type's, doing double work.
By chaining together multiple DecayedType's and FunctionProtoType's, this would
result in 2^N Type's visited only N DecayedType's and N FunctionProtoType's
exsit. Another bug where VisitDecayedType and VisitAdjustedType did
redundant work doubled the work at each level, giving 4^N Type's visited. This

this patch adds support for the explicit bool specifier.

- The parsing for the explicit(bool) specifier was added in ParseDecl.cpp.
- The storage of the explicit specifier was changed. the explicit specifier was stored as a boolean value in the FunctionDeclBitfields and in the DeclSpec class. now it is stored as a PointerIntPair<Expr*, 2> with a flag and a potential expression in CXXConstructorDecl, CXXDeductionGuideDecl, CXXConversionDecl and in the DeclSpec class.
- Following the AST change, Serialization, ASTMatchers, ASTComparator and ASTPrinter were adapted.
- Template instantiation was adapted to instantiate the potential expressions of the explicit(bool) specifier When instantiating their associated declaration.
- The Add*Candidate functions were adapted, they now take a Boolean indicating if the context allowing explicit constructor or conversion function and this boolean is used to remove invalid overloads that required template instantiation to be detected.
- Test for Semantic and Serialization were added.

template constexpr bool is_same_v<int, int>;
Before this change, when emitting debug info for the
`is_same_v<int, int>` global variable, clang would crash because it
would try to use the template parameter list from the partial
specialization to give parameter names to template arguments. This
doesn't work in general, since a partial specialization can have fewer
arguments than the primary template. Therefore, always use the primary
template. Hypothetically we could try to use the parameter names from
the partial specialization when possible, but it's not clear this really
helps debugging in practice.

lib/Header: Fix Visual Studio builds try #2
Summary:
This is a follow up to r355253 and a better fix than the first attempt
which was r359257.
We can't install anything from ${CMAKE_CFG_INTDIR}, because this value
is only defined at build time, but we still must make sure to copy the
headers into ${CMAKE_CFG_INTDIR}/lib/clang/$VERSION/include, because the lit
tests look for headers there. So for this fix we revert to the
old behavior of copying the headers to ${CMAKE_CFG_INTDIR}/lib/clang/$VERSION/include
during the build and then installing them from the source tree.

Variable auto-init: don't initialize aggregate padding of all aggregates
Summary:
C guarantees that brace-init with fewer initializers than members in the
aggregate will initialize the rest of the aggregate as-if it were static
initialization. In turn static initialization guarantees that padding is
initialized to zero bits.
Quoth the Standard:
C17 6.7.9 Initialization ❡21
If there are fewer initializers in a brace-enclosed list than there are elements
or members of an aggregate, or fewer characters in a string literal used to
initialize an array of known size than there are elements in the array, the
remainder of the aggregate shall be initialized implicitly the same as objects
that have static storage duration.
C17 6.7.9 Initialization ❡10
If an object that has automatic storage duration is not initialized explicitly,
its value is indeterminate. If an object that has static or thread storage
duration is not initialized explicitly, then:
* if it has pointer type, it is initialized to a null pointer;
* if it has arithmetic type, it is initialized to (positive or unsigned) zero;
* if it is an aggregate, every member is initialized (recursively) according to
these rules, and any padding is initialized to zero bits;
* if it is a union, the first named member is initialized (recursively)
according to these rules, and any padding is initialized to zero bits;

Since, according to my short research,
"The vector_size attribute is only applicable to integral and float scalars,
although arrays, pointers, and function return values are allowed in conjunction
with this construct."
[src: https://gcc.gnu.org/onlinedocs/gcc-4.6.1/gcc/Vector-Extensions.html#Vector-Extensions]

[analyzer] Treat functions without run-time branches as "small".
Currently we always inline functions that have no branches, i.e. have exactly
three CFG blocks: ENTRY, some code, EXIT. This makes sense because when there
are no branches, it means that there's no exponential complexity introduced
by inlining such function. Such functions also don't trigger various fundamental
problems with our inlining mechanism, such as the problem of inlined
defensive checks.
Sometimes the CFG may contain more blocks, but in practice it still has
linear structure because all directions (except, at most, one) of all branches
turned out to be unreachable. When this happens, still treat the function
as "small". This is useful, in particular, for dealing with C++17 if constexpr.
