Previous implementation to filter decls not in the main file did not
work in the case where a template was instantiated from a header in the
main file. It would than include that function/class in topLevelDecls.

Summary:
- when we hit the cache, the reported filename should be that of the
cache query, not that of the cache store. This matches behaviors of
common FSes, and avoids triggering difficult edge cases in
FileManager when files are being moved around concurrently.
- filename comparisons (both cache queries and == mainfile checks)
should fold away . and .. in paths. These can appear when relative
paths occur in compile_commands.json. (gn does this).

Summary:
Previously, when we rename a macro, we get an error message of "there is
no symbol found".
This patch improves the message of this case (as we don't support macros).

Summary:
Delete the begin-end form because the standard std::partition_point
can be easily used as a replacement.
The ranges-style llvm::bsearch will be renamed to llvm::partition_point
in the next clean-up patch.
The name "bsearch" doesn't meet people's expectation because in C:
> If two or more members compare equal, which member is returned is unspecified.

De-duplicate comments and declaration locations in reduce function.
When two files include the same header file, this file's content is mapped
twice causing comments and locations to be duplicated after the reduce stage.

Summary:
Failing case:
```
#include "foo.h"
void fo^o() {}
```
getRenameDecl() returns the decl of the symbol under the cursor (which is
in the current main file), instead, we use the canonical decl to determine
whether a symbol is declared in #included header.

Summary:
- nodes can have special-cased hit ranges including "holes" (FunctionTypeLoc in void foo())
- token conflicts between siblings (int a,b;) are resolved in favor of left sibling
- parent/child overlap is handled statefully rather than explicitly by comparing parent/child
ranges (this lets us share a mechanism with sibling conflicts)

The bitstream reader handles errors poorly. This has two effects:
* Bugs in file handling (especially modules) manifest as an "unexpected end of
file" crash
* Users of clang as a library end up aborting because the code unconditionally
calls `report_fatal_error`
The bitstream reader should be more resilient and return Expected / Error as
soon as an error is encountered, not way late like it does now. This patch
starts doing so and adopting the error handling where I think it makes sense.
There's plenty more to do: this patch propagates errors to be minimally useful,
and follow-ups will propagate them further and improve diagnostics.

Summary: Tidy check behavior often depends on language and/or clang-tidy options. This revision allows a user of TranformerClangTidyCheck to pass rule _generator_ in place of a rule, where the generator takes both the language and clang-tidy options. Additionally, the generator returns an `Optional` to allow for the case where the check is deemed irrelevant/disable based on those options.

Summary:
Currently, `clang::tidy::test::runCheckOnCode()` constructs the check
instances *before* initializing the ClangTidyContext. This ordering causes
problems when the check's constructor accesses the context, for example, through
`getLangOpts()`.
This revision moves the construction to after the context initialization, which
follows the pattern used in the clang tidy tool itself.

In serialize::parseBases(...), when a base record is a template
specialization, the specialization was used as the parent. It should be
the base template so there is only one file generated for this record.
When the specialized template is implicitly declared the reference USR
corresponded to the GlobalNamespace's USR, this will now be the base
template's USR.
More information about templates will be added later.
In serialize::emiInfo(RecorDecl*, ...), typedef records were not handled
and the name was empty. This is now handled and a IsTypeDef attribute is
added to RecordInfo struct.
In serialize::emitInfo(CXXMethodDecl*, ...), template specialization is
handled like in serialize::parseBases(...).
Bitcode writer and reader are modified to handle the new attribute of
RecordInfo.
