The performance of the cppcheck --dump function is significantly degraded

[zhouming]

I tested three versions of cppcheck for dump output of source files, 1.9, 2.2, and 2.6, and found that the efficiency of the dump function was significantly reduced. I suggest that the new version be optimized.
cmd: cppcheck -f --language=c++ --dump src_dir
I test same 22 src files in src_dir, and get the time consume:
version 1.9: 0.9655min
version 2.2: 1.2828min
version 2.6: 2.7085min

If you wonder why Cppcheck 2.6 takes 2.7085min I suggest that you run with the option --showtime=summary. I would assume that ValueFlow is taking much more time.

OK, I will try it.
But based on my tests last week, I found that some source file failed to generate dump files in one night(ver2.6).
So it seems abnarmal.
