plind44@gmail.com 0edbf9e709 MIPS: Skip some conditional deopts for Div/Mul when all uses are truncating. 
Port r15060 (8cdd204)

Original commit message:
- set "can be minus zero" flag properly so minus-zero checks are skipped
- skip "integer result?" check in division code when uses are truncating
- drive-by cleanup: consolidated computation of kCanOverflow flag for Add/Sub into range inference phase
