I got error messages while building `cppcheck 2.12.0` for RISC-V Arch
Linux:

I found out the reason is that the testcases were designed for
x86/x86_64 or other `signed char` platforms (i.e. default character type
is `signed char` ), whereareas RISC-V is an `unsigned char` platform,
which causes different behavior in
`lib/valueflow.cpp:valueFlowImpossibleValues`. I'm not sure whether this
error leads from a functional bug, so if you have a better approach to
fix it, please let me know.
Maybe you could reproduce this error on x86_64 platform by setting
`defaultSign = 'u';` in `Platform::set(Type t)`.
The name was misleading as it was actually a `long long` and also if we
ever move to an (optional) 128-bit value it wouldn't even less fitting.
We should name it to match our alias type.
This is a step onto leveraging the `ThreadExecutor` implementation for
`ProcessExecutor` which is a follow-up to #4870. We need to have the
proper test coverage and the existing implementations working as
expected before we move to the shared code.
Fixes:
- added `--showtime=` tests for all executor implementations
- only print `--showtime=summary` once at the end
- prevents `--showtime=` by multiple threads to be written at the same
time - essentially breaking the output
- reset the timer results before each test
- deprecated `top5` in favor of `top5_file`
- fixed printing for all executors except `ProcessExecutor`
This is in preparation of avoiding accessing `std::cout` directly as
well as streamlining and improving the logging during the settings
parsing. There are no functional changes yet.
Based on #4701, #5418
A helper function for the `isdigit()` test should be introduced on the
simplecpp side.

We were calling several interface functions through their inherited
classes instead of using the base classes requiring us to add `friend`
declarations to make the implementations accessible. This adjusts
several of those cases.
