The difference is that with 'readonly' the JIT knows the value of the static
field can't change, so it embeds the value into the JITted code, without
readonly, it needs to emit a load instruction to load the value. No idea why
that makes a difference, the value is constant anyway, since it is initialized
in the type initializer of SharedCounter, which is called after Main was JIT
compiled.
