reporters: silence -Wsubobject-linkage

2024-01-15T08:57:30+00:00

gcc emits `Wsubobject-linkage`, because the the publicly visible
`TablePrinter` contains `ColumnInfo`, which is part of an anonymous
namespace

Remove redundant destructors

2024-01-14T22:33:51+00:00

Classes will automatically inherit the virtual-ness of their base
class destructors. If the base class already has a virtual
destructor and the derived class needs default destructor semantics
then the derived class can omit defining the destructor in favor of
the compiler automatically defining it.

This has an additional benefit of reenabling move semantics. The
presence of a user-specified destructor automatically disables move
operations.

Move-enable various parts of TextFlow

This removes about 200 pointless copies from printing the help
message (the original motivation for the change), and also nicely
improves performance of the various reporters that depend on
TextFlow.

Make it clearer that the JSON reporter is WIP

JSONWriter deals in StringRefs instead of std::strings

2023-11-17T08:54:03+00:00

Together with liberal use of `_sr` UDL to compile-time convert
string literals into StringRefs, this will reduce the number of
allocation and remove most of the strcpy calls inherent in
converting string lits into `std::string`s.

Flush stream after benchmarkStarting in ConsoleReporter

2023-08-13T21:09:02+00:00

This means that the user will see the estimation of full benchmark
running time when it is available, unlike now when it often only
ends up flushed after the benchmark is fully finished.

This means that the user will almost immediately see the start
of table like this

```
benchmark name                       samples       iterations    estimated
                                     mean          low mean      high mean
                                     std dev       low std dev   high std dev
-------------------------------------------------------------------------------
Fill vector generated                          100            54     3.0834 ms
```

This presents significant improvement in user experience especially
for long running benchmarks.
