Fix hwasan/ubsan issue Fix left shift of values >127 by 24. The intermediary "unsigned char" got promoted "int", which was then left-shifted by 24, thus extending into the sign bit, before being assigned back to an unsigned int. Explicitly cast the intermediary to an unsigned int to avoid the problem. Bug: 134892789 Test: assembly code is identical Change-Id: Ifde58385cbededb4cc8672163d2198cd91bf3c97
