Subject: Revert "[TableGen] Use cast instead of dyn_cast where result isn't checked before... 
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=0b67fe729322ef415ee59a87619795136a1def4f;p=oota-llvm.git

Revert "[TableGen] Use cast instead of dyn_cast where result isn't checked before being dereferenced."

Turns out I misread the parentheses. Though I'm pretty sure its always a RecordRecTy and non of the callers really seem to expect null. But until I'm completely sure I'm going to revert this.
