Chandler Carruth 3f5e7b1fb6 [PM] Use a SmallVector instead of std::vector to avoid heap allocations 
for small switches, and avoid using a complex loop to set up the
weights.

We know what the baseline weights will be so we can just resize the
vector to contain all that value and clobber the one slot that is
likely. This seems much more direct than the previous code that tested
at every iteration, and started off by zeroing the vector.
