Disable irrelevant Cray compiler warnings if cc-silence is enabled
Cray is pretty warning-happy, so disable ones that aren't helpful. Each warning
has a numeric value instead of having named flags to disable specific warnings.
Disable warnings 128 and 1357.
128: Ignore unreachable code warning. Cray warns about `not_reached()` not
being reachable in a couple of places because it detects that some loops
will never terminate.
1357: Ignore warning about redefinition of malloc and friends
With this patch, Cray 8.4.0 and 8.5.1 build cleanly and pass `make check`
