Description

See https://bitbucket.org/marshallpierce/groovy-int-increment-decrement for a simple test case.

See https://bitbucket.org/marshallpierce/groovy-int-increment-decrement/src/11bf750fb3a14441598841f819aca7b2f88f9474/src/main/groovy/IntIncrementDecrementTest.groovy?at=master for the source in question.

It seems like if it's determining types statically, then it should know that i and j are ints, and that the type of i++ and ++j should also be int.
