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".

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.

This relands r250831 after some fixes to shrink the ParentMap overall
with one addtional tweak: nodes with pointer identity (e.g. Decl* and
friends) can be store more efficiently so I put them in a separate map.
All other nodes (so far only TypeLoc and NNSLoc) go in a different map
keyed on DynTypedNode. This further uglifies the code but significantly
reduces memory overhead.
Overall this change still make ParentMap significantly larger but it's
nowhere as bad as before. I see about 25 MB over baseline (pre-r251008)
on X86ISelLowering.cpp. If this becomes an issue we could consider
splitting the maps further as DynTypedNode is still larger (32 bytes)
than a single TypeLoc (16 bytes) but I didn't want to introduce even
more complexity now.

Putting DynTypedNode in the ParentMap bloats its memory foot print.
Before the void* key had 8 bytes, now we're at 40 bytes per key which
can mean multiple gigabytes increase for large ASTs and this count
doesn't even include all the added TypeLoc nodes. Revert until I come
up with a better data structure.
This reverts commit r250831.
llvm-svn: 250889
Firstly this changes the type of parent map to be keyed on DynTypedNode to
simplify the following changes. This comes with a DenseMapInfo for
DynTypedNode, which is a bit incomplete still and will probably only work
for parentmap right now.
Then the RecursiveASTVisitor in ASTContext is updated and finally
ASTMatchers hasParent and hasAncestor learn about the new functionality.
Now ParentMap is only missing TemplateArgumentLocs and CXXCtorInitializers.

Summary:
Remove unnecessary wrapping for the 0 and 1 matcher cases of

Refactor TrueMatcher to take advandage of the new conversions between
DynTypedMatcher and Matcher<T>. Also, make it a singleton.

Summary:
This change introduces DynMatcherInterface and changes the internal
representation of DynTypedMatcher and Matcher<T> to use a generic
interface instead.
It removes unnecessary indirections and virtual function calls when
converting matchers by implicit and dynamic casts.
DynTypedMatcher now remembers the stricter type in the chain of casts
and checks it before calling into DynMatcherInterface.
This change improves our clang-tidy related benchmark by ~14%.
Also, it opens the door for more optimizations of this kind that are
coming in future changes.
As a side effect of removing these template instantiations, it also
speeds up compilation of Dynamic/Registry.cpp by ~17% and reduces the
number of
symbols generated by ~30%.

This library supports all the features of the compile-time based ASTMatcher
library, but allows the user to specify and construct the matchers at runtime.
It contains the following modules:
- A variant type, to be used by the matcher factory.
- A registry, where the matchers are indexed by name and have a factory method
with a generic signature.
- A simple matcher expression parser, that can be used to convert a matcher
expression string into actual matchers that can be used with the AST at
runtime.
Many features where omitted from this first revision to simplify this code
review. The main ideas are still represented in this change and it already has
support working use cases.
Things that are missing:
- Support for polymorphic matchers. These requires supporting code in the
registry, the marshallers and the variant type.
- Support for numbers, char and bool arguments to the matchers. This requires
supporting code in the parser and the variant type.
- A command line program putting everything together and providing an already
functional tool.
