[cleanup] Global variable declarations are never hole initialized

[cleanup] Global variable declarations are never hole initialized

Globals used to be hole-initialized in the case of toplevel legacy
const declarations. But now that the only use of legacy const is
for sloppy function expression names, we can unconditionally
initialize globals to undefined instead of the_hole.
