test: skip rangegen.go on 32-bit platforms #64789
Description
The test $GOROOT/test/rangegen.go has been causing problems on 32-bit platforms as part of release generation workflows. Looking at this test, it generates a very large file (242k lines) and compiles it, which is going to stress smaller 32-bit machines. This bug is to track the task of adding a skip for this test on 32-bit architectures.
