[PATCH] Fix match with result operands and conditions

[Richard Biener]

Currently the code generated for the following (stupid example)

(match (integer_zerop @0)
 INTEGER_CST@0
 (if (integer_zerop (@0))))

is wrong in not assigning anything to the result @0.  The following
obvious patch fixes that.  We don't have a match pattern like the
above so it doesn't affect generated code.

Applied.

Richard.
