SimplifyGlobals: Fold single-use globals to their use (#6023)
For example,
(global $a (struct.new $A))
(global $b (struct.new $B (global.get $A)))
=>
(global $b (struct.new $B (struct.new $A)))
and the global $a is now unused. This is valid if $a has no other uses.
This saves a little in code size, but should not really help otherwise, as we
already look through immutable global.get operations in important
optimizations. But the code size may matter if there are many such single-
use globals.
