cmd/compile: in wasm, allocate approximately right number of locals for functions
Currently, WASM binary writer requests 16 int registers (locals) and
16 float registers for every function regardless of how many locals the
function uses.
This change counts the number of used registers and requests a number
of locals matching the highest register index. The change has no effect
on performance and neglectable binary size improvement, but it makes
WASM code more readable and easy to analyze.
