information gets recorded in our Reloc structs.) Therefore, in order to
properly dedup CFStrings, we create a mutable copy of the CFString and
zero out the embedded addends before performing any hashing / equality
checks.

(We did in fact have a partial implementation of CFString deduplication
already. However, it only worked when the cstrings they point to are at
identical offsets in their object files.)

I anticipate this approach can be extended to other similar

In addition, we previously treated all references with differing addends
as unequal. This is not true when the references are to literals:
different addends may point to the same literal in the output binary. In

Add JSON output option to llvm-remark-size-diff

The goal here is to make it easy for external tools to consume output from
llvm-remark-size-diff. These tools could be used for automated size analysis.
(E.g. in CI).

To specify JSON output, use `--report_style=json`. JSON output can be
pretty-printed via `--pretty`.

With automation in mind, the schema looks like this:

```

  "A": <filename_a>
  "B": <filename_b>
},

"InBoth": [
   {
    "FunctionName": <function name>,

       0,
       <count_in_b>
     ]
   },
   ...
]
```

A few notes:

- Filenames are included, because tools may want to combine many outputs
  together in some way (a big JSON file, a big CSV, or something.)

- Counts are represented as [a, b] so that a diff can be calculated via b - a.
  The original counts may be useful for size analysis (e.g. was this function
  extremely large before?) and so both are preserved.

- `OnlyInA` and `OnlyInB` have a 0 for one of the counts always. This is to
  make it easier for tools to share code between `OnlyInA`, `OnlyInB`, and

When a structure constructor does not initialize an allocatable component,
ensure that the typed expression representation contains an explicit
NULL() for the component.  Expression semantics already copies default
initialized expressions for nonallocatable components into structure

[sancov] Don't instrument calls to bitcast funcs: they're not indirect.

Currently, when instrumenting indirect calls, this uses
CallBase::getCalledFunction to determine whether a given callsite is
eligible.

However, that returns null if:
  this is an indirect function invocation or the function signature
  does not match the call signature.

So, we end up instrumenting direct calls where the callee is a bitcast
ConstantExpr, even though we presumably don't need to.

Use isIndirectCall to ignore those funky direct calls.
