Assume the shared library path variable is LD_LIBRARY_PATH on systems
except Darwin and Windows.  This prevents inserting an environment
variable with an empty name (which is illegal and leads to a Python
exception) on any of the BSDs.

Fixing parameters in clang-tidy fuchsia-overloaded-operator test case

Adds a check to the Fuchsia module to warn if an operator is overloaded,
except move and copy operators.

Summary:
The tools is used to generate global symbols for clangd (global code completion),
The format is YAML, which is only for **experiment**.

Usage:
./bin/global-symbol-builder </path/to/llvm-dir> > global-symbols.yaml

TEST:
used the tool to generate global symbols for LLVM (~72MB).

Summary:
The goal here is again to make it easier to read and write the tests.

I've extracted `parseTextMarker` from CodeCompleteTests into an `Annotations`
class, adding features to it:
  - as well as points `^s` it allows ranges `[[...]]`
  - multiple points and ranges are supported
  - points and ranges may be named: `$name^` and `$name[[...]]`

These features are used for the xrefs tests. This also paves the way for
replacing the lit diagnostics.test with more readable unit tests, using named
ranges.

Alternative considered: `TestSelectionRange` in clang-refactor/TestSupport
Main problems were:
 - delimiting the end of ranges is awkward, requiring counting
 - comment syntax is long and at least as cryptic for most cases
 - no separate syntax for point vs range, which keeps xrefs tests concise
 - Still need to convert to Position everywhere
 - Still need helpers for common case of expecting exactly one point/range

(I'll probably promote the extra `PrintTo`s from some of the core Protocol types
into `operator<<` in `Protocol.h` itself in a separate, prior patch...)

Examples:
* Always evaluates to 0:

```
  int X;
  if (0 & X) return;
```

* Always evaluates to ~0:

```
  int Y;
  if (Y | ~0) return;
```

* The symbol is unmodified:

```
  int Z;
  Z &= ~0;
```

Supports a comma-separated list of check names to be disabled on the given line. Also supports * as a wildcard to disable all lint diagnostic messages on that line.
