Michael Munday 5654114d04 cmd/compile: use math/bits functions where possible 
Use the math/bits functions to calculate the number of leading/
trailing zeros, bit length and the population count.

The math/bits package is built as part of the bootstrap process
so we do not need to provide an alternative implementation for
Go versions prior to 1.9.

Passes toolstash-check -all.
