Summary: This patch contains 2 separate changes: 1) the initializer of a variable should play no part in decl "invalid" bit; 2) preserve the invalid initializer via recovery exprs; With 1), we will regress the diagnostics (one big regression is that we loose the "selected 'begin' function with iterator type" diagnostic in for-range stmt; but with 2) together, we don't have regressions (the new diagnostics seems to be improved).
