Omit ‘const’ on locals

Omit ‘const’ on locals

Remove ‘const’ qualifier from locals that were newly added.
We don’t normally bother declaring locals with ‘const’ even
though they are not modified, for the same reason we don’t
bother declaring them with ‘register’ even though their
addresses are not taken; the advantage in compile-time
checking isn’t worth the loss of readability.
