Fixed another assert exposed by fuzzing. The utility function getRegisterEnum()
was asserting because the (RegClass, RegNum) combination doesn't make sense from an encoding point of view. Since getRegisterEnum() is used all over the place, to change the code to check for encoding error after each call would not only bloat the code, but also make it less readable. An Err flag is added to the ARMBasicMCBuilder where a client can set a non-zero value to indicate some kind of error condition while building up the MCInst. ARMBasicMCBuilder::BuildIt() checks this flag and returns false if a non-zero value is detected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101290 91177308-0d34-0410-b5e6-96231b3b80d8
