2018-03-07[formcalc] Consider width along with depth of treeDan Sinclair
When building the formcalc parser trees we need to limit on width along with depth. It's possible to generate a tree of a single depth but is more then 20k nodes wide. This will eventuall cause stack overflow issues. This CL re-uses the depth check for the grammar expressions in which we're extending the width of the tree we count that against our depth check.

2018-03-07[formcalc] Handle bad elseif conditionalschromium/3365Dan Sinclair
This Cl adds checking for the conditionals of if and elseif expressions. If the conditional fails to parse we should return nullptr. This already happens by accident in the if() case, but with elseif() conditions we'll fail the ASSERT in the CXFA_FMIfExpression constructor and crash. This CL explicitly checks for the expressions and early exists if they failed to parse.
