We are currently getting:
`clang: error: invalid argument '-fsanitize-minimal-runtime' not allowed with
'-fsanitize=implicit-conversion'`
when running
`-fsanitize=implicit-conversion -fsanitize-minimal-runtime`
because `implicit-conversion` now includes `implicit-bitfield-conversion` which
is not included in the `integer` check. The `integer` check includes the
`implicit-integer-conversion` checks and is supported by the trapping option
and because of that compatible with the minimal runtime. It is thus reasonable
to make `implicit-bitfield-conversion` compatible with the minimal runtime.

Subject: [PATCH] [clang][UBSan] Make sure that the implicit-conversion group
is compatible with minimal runtime
