SimplifyGlobals: Handle nested read-only-to-write patterns (#4365)
The general pattern is
if (!global) { global = 1 }
This PR generalizes that to handle nested appearances,
if ({
if (!global) { global = 1 }
!global
}) {
global = 1
}
With this I can finally see no more "once" global operations on the hottest
function in the currently slowest j2wasm benchmark ("filter").
Also added a failing testcase for something we do not handle yet.
