temporarily disable failing math.mininteger related tests
Browse files Browse the repository at this point in the history
This is due to a floating point to integer conversion bug in
libcompiler-rt. The following command prints
`RUST_LOG=debug ckb-debugger --max-cycles 2000000000 --bin ./build/lua-loader.debug -- -e 'print(math.mininteger + 0.0)'`
`-2.3058430090000e+18` instead of `-9.2233720368548e+18`.
The latest commit a3fb2348b19167dfb027e20f8e1306ebbf31cfbf of llvm
fixed this bug. But we have not picked the newest code from llvm yet.
