fix -IV_MIN negations
Doing uv = -iv is undefined behaviour if iv happens to be IV_MIN.
This occurs in several places in the perl sources.
Found by -fsanitize=undefined.
Here's a typical message:
sv.c:2864:7: runtime error: negation of -9223372036854775808 cannot be represented in type 'IV' (aka 'long'); cast to an unsigned type to negate this value to itself
