8022395: java.util.zip.ZipException: Not in GZIP format in JT_JDK/test/java/util/zip/GZIP tests Reviewed-by:

C1's instrinsic for java.util.zip.CRC32.update(int b) on x86 destroys the input value b but the register is not marked to be destroyed. This can lead to a wrong value if CRC32.update is inlined.

The fix is to mark the LIRItem to be destroyed. This will make C1 to insert a spill move.
