This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
Unlike Header, we really do have a preferred spelling for an include: the one
that we used to open the file.
The fact that Header is still FileEntry* makes it difficult to accidentally
use path equality when we want inode equality.

The fixIncludes was using the `input` as the main file path, this will
results in inserting header at wrong places.
We need the main file path to so that we can get the real main-file
header.

Make sure unresolved headers are not analyzed as part of unused
includes.
Also introduces a testing fixture for analyze tests

This adds command-line flags to the tool:
+ -print: prints changed source code
+ -print=changes: prints headers added/removed
+ -edit: rewrites code in place
+ -insert=0/-remove=0: disables additions/deletions for the above
These are supported by a couple of new functions dumped into Analysis:
analyze() sits on top of walkUsed and makes used/unused decisions for
Includes. fixIncludes() applies those results to source code.

We preserve decls for stdlib symbols after this patch in symbol. That
way we have a more unified view of stdlib and regular decls and can provide
reacher information in applications.

- replace SymbolLocation std::variant with enum-exposing version similar to
those in types.cpp. There's no appropriate implementation file, added
LocateSymbol.cpp in anticipation of locateDecl/locateMacro.
- FindHeaders is not part of the public Analysis interface, so should not
be implemented/tested there (just code organization)
- rename findIncludeHeaders->findHeaders to avoid confusion with Include concept

This patch implements the initial version of "Location => Header" step:
- define the interface;
- integrate into the existing workflow, and use the PragmaIncludes;

RefTypes are distinct categories for each reference to a symbol. They
are signals indicating strength of a reference, that'll enable different
decision making based on the finding being provided.
There are 3 kinds of ref types:
- Explicit, the reference is spelled in the code.
- Implicit, the reference is not directly visible in the code.
- Ambigious, the reference exists but can't be proven as used (e.g.
overloads brought in by a using decl but not used by the code).

Introduces walkUsed, a very simple version of the public API to enable
incremental development on rest of the pieces.
