use lookup table for malloc bin index instead of float conversion
float conversion is slow and big on soft-float targets. The lookup table increases code size a bit on most hard float targets (and adds 60byte rodata), performance can be a bit slower because of position independent data access and cpu internal state dependence (cache, extra branches), but the overall effect should be minimal (common, small size allocations should be unaffected).
