Compiler [optimizer]: Disabled some broken peep rules.

These peep hole optimizer rules weren't protected against
negation overflow.

Disabled since INT32_NEG_OVERFLOW() doesn't exist in Pike 7.8.

Cf Pike 7.9.5 and later commit c63deca838788875b37d48a4faa044b5d6cafa0b.

Thanks to Magnus Holmgren for the report.

Potential fix for [LysLysKOM 21868180] (infinite optimizer loop).
