Since GCC version 10, there has been a new option -fanalyzer for
static analysis. It can make the CI pipeline more comprehensive.
Also, the static analysis updates in GCC 11, but we cannot install
the GCC 11 in ubuntu 20.04 straightforwardly right now, which is
the GitHub workflow environment (see status-check.yaml).
For this reason, we stay at the GCC 10.
Close #117
