Subject: Remove unnecessary null check.  NFC.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=b0fd31a910a0f241019ec88a82d0c9d611ea22d0;p=oota-llvm.git

Remove unnecessary null check.  NFC.

Since both places which set this variable do so with dyn_cast, and not
dyn_cast_or_null, its impossible to get a nullptr here, so we can remove
the check.
