Support hint for inline if statement

[ZeroRin]

Consider typing the following code in VSCode

foo = True
bar = 1 if foo else 0

There will be no hint available when typing foo

Also, the typed foo will not be recognized as variable until the statement after else is written

I've improved the parser's error recovery in this case so it creates a TernaryNode (with error subnodes) when it is discovers a partial ternary expression. This provides the completion provider with sufficient parse information to supply completion suggestions in this circumstance.
