Two new matchers for `CXXNewExpr` are added which may be useful e.g. in
`clang-tidy` checkers. One of them is `isArray` which matches `new[]` but not
plain `new`. The other one, `hasArraySize` matches `new[]` for a given size.

Internal linkage variables ODR referenced from inline functions create
ODR violations (the same inline function ends up having different
definitions in each TU, since it references different variables - rather
than one definition).
This also happens to break modular code generation - so this is the last
fix to allow clang to compile with modular code generation.
llvm-svn: 318304
Summary:
This allows `linkageSpecDecl` to be used from `clang-query`.
See also D31869 which similary adds `isStaticStorageClass`.

Summary:
This allows the clang-query tool to use matchers like
"integerLiteral(equals(32))". For this to work, an overloaded function
is added for each possible parameter type.

Summary:
Needed to support something like "floatLiteral(equals(1.0))". The
parser for floating point numbers is kept simple, so instead of ".1" you
have to use "0.1".

Summary:
Recognize boolean literals for future extensions ("equals(true)").
Note that a specific VariantValue constructor is added to resolve
ambiguity (like "Value = 5") between unsigned and bool.

Summary:
This adds a new ASTMatcher for CXXStdInitializerListExprs that matches C++ initializer list expressions.
The primary motivation is to use it to fix [[ https://bugs.llvm.org/show_bug.cgi?id=32896 | PR32896 ]] (review here [[ https://reviews.llvm.org/D32767 | D32767 ]]).

This diff registers isConstexpr matcher.
Test plan:
make check-all
check that "match varDecl(isConstexpr())"
works in clang-query

Summary:
I needed to know whether a FieldDecl had an in-class
initializer for D26453. I used a narrowing matcher there, but a
traversal matcher might be generally useful.

Summary: Matcher proposed in the review of checker misc-assign-operator (name pending). Its goal is to find the direct enclosing function declaration of a statement and run the inner matcher on it. Two version is attached in this patch (thus it will not compile), to be decided which approach to take. The second one always chooses one single parent while the first one does a depth-first search upwards (thus a height-first search) and returns the first positive match of the inner matcher (thus it always returns zero or one matches, not more). Further questions: is it enough to implement it in-place, or ASTMatchersInternals or maybe ASTMatchFinder should be involved?

Summary:
Prevent hasAncestor from comparing nodes that are not supported.
hasDescendant was fixed some time ago to avoid this problem.
I'm applying the same fix to hasAncestor: if any object in the Builder map is
not comparable, skip the cache.

Summary:
llvm::VariadicFunction is only being used by ASTMatchers.
Having our own copy here allows us to remove the other one from llvm/ADT.
Also, we can extend the API to meet our needs without modifying the common
implementation.

Summary: A checker (will be uploaded after this patch) needs to check implicit casts. Existing generic matcher "has" ignores implicit casts and parenthesized expressions and no specific matcher for matching return value expression preexisted. The patch adds such a matcher (hasReturnValue).
