I am just reporting this phenomenon and I am not sure whether it is caused by 
my bad configurations.
Under my configurations, the last step of `make check-all` will execute 
`llvm-lit` with argument `--param USE_Z3_SOLVER=0`, which will make all test 
cases requiring z3 skipped.
Although, clang is built with z3 under this configuration.

Can we automatically enable all test cases requiring z3 if clang is built with 
z3? I do not think the patch D83677 <https://reviews.llvm.org/D83677> really 
make the problem fixed.
