Disable floating-point overflow checks #3620

Description

@cospectrum

Is there a way to specifically disable the floating-point overflow checks?
I only want to ignore the following errors (and nothing else):

Failed Checks: NaN on multiplication
Failed Checks: NaN on addition
Failed Checks: arithmetic overflow on floating-point addition
Failed Checks: arithmetic overflow on floating-point multiplication

If it's not possible, is there a way to implement custom add/mul functions to make kani happy? Any tips.
