[PATCH] Fix genmatch code-gen for [VEC_]COND_EXPR

[Richard Biener]

The following fixes the pattern recognition code-gen for GIMPLE
[VEC_]COND_EXPR which can have either a SSA name condition or
an embedded GENERIC expression (ugh).

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress (we
don't have any pattern matching the condition part).

Richard.
