Updates the return types of these matchers' definitions to use
`internal::Matcher<LambdaCapture>` instead of `LambdaCaptureMatcher`. This
ensures that they are categorized as traversal matchers, instead of narrowing
matchers.

This contributes follow-up work from https://reviews.llvm.org/D112491, which
allows for increased control over the matching of lambda captures. This also

This provides better support for `LambdaCapture`s by making them first-
class and allowing them to be bindable. In addition, this implements several
`LambdaCapture`-related matchers. This does not update how lambdas are
traversed. As a result, something like trying to match `lambdaCapture()` by
itself will not work - it must be used as an inner matcher.

The new matcher additionally covers blocks and Objective-C methods.
This matcher actually makes sure that the statement truly belongs
to that declaration's body. forFunction() incorrectly reported that
a statement in a nested block belonged to the surrounding function.
forFunction() is now deprecated due to the above footgun, in favor of
forCallable(functionDecl()) when only functions need to be considered.

This is a simple utility which allows matching on binaryOperator and
cxxOperatorCallExpr. It can also be extended to support
cxxRewrittenBinaryOperator.
Add generic support for MapAnyOfMatchers to auto-marshalling functions.

Make it possible to compose a matcher for different base nodes.
This accepts one or more node matcher functors and zero or more
matchers, composing the latter into the former.
This allows composing of matchers where the same inner matcher name is
used for the same concept, but with a different node functor. Currently,
there is a limitation that the nodes must be in the same "clade", so
while
mapAnyOf(ifStmt, forStmt).with(hasBody(stmt()))
can be used, functionDecl can not be added to the tuple.
It is possible to use this in clang-query, but it will require changes
to the QueryParser, so is deferred to a future review.

This allows ASTs to be merged when they contain GenericSelectionExpr
nodes (this is _Generic from C11). This is needed, for example, for
CTU analysis of C code that makes use of _Generic, like the Linux
kernel.
The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter. Additionally, this change adds support for structural
equivalence of _Generic in the AST.

The static_assert in "libcxx/include/memory" was the main offender here,
but then I figured I might as well `git grep -i instantat` and fix all
the instances I found. One was in user-facing HTML documentation;
the rest were in comments or tests.
traverse() predates the IgnoreUnlessSpelledInSource mode. Update example
and test code to use the newer mode.

Made the isExpandedFromMacro matcher work on Stmt's, TypeLocs and Decls in line with the other macro expansion matchers.
Also tweaked it to take a `std::string` instead of a `StringRef`.
This prevents potential use-after-free bugs if the matcher is created with a string thats destroyed before the matcher finishes matching.

The analysis for const-ness of local variables required a view generally useful
matchers that are extracted into its own patch.
They are decompositionDecl and forEachArgumentWithParamType, that works
for calls through function pointers as well.
This is a reupload of https://reviews.llvm.org/D72505, that already landed,
but had to be reverted due to a GCC crash on powerpc
(https://reviews.llvm.org/rG4c48ea68e491cb42f1b5d43ffba89f6a7f0dadc4)
Because this took a long time to adress, i decided to redo this patch and
have a clean workflow.
I try to coordinate with someone that has a PPC to apply this patch and
test for the crash. If everything is fine, I intend to just commit.
If the crash is still happening, i hope to at least find the cause.

Added new Macros `AST(_POLYMORPHIC)_MATCHER_REGEX(_OVERLOAD)` that define a matchers that take a regular expression string and optionally regular expression flags. This lets users match against nodes while ignoring the case without having to manually use `[Aa]` or `[A-Fa-f]` in their regex. The other point this addresses is in the current state, matchers that use regular expressions have to compile them for each node they try to match on, Now the regular expression is compiled once when you define the matcher and used for every node that it tries to match against. If there is an error while compiling the regular expression an error will be logged to stderr showing the bad regex string and the reason it couldn't be compiled. The old behaviour of this was down to the Matcher implementation and some would assert, whereas others just would never match. Support for this has been added to the documentation script as well. Support for this has been added to dynamic matchers ensuring functionality is the same between the 2 use cases.
