<pre>When the 3rd argument to binsri / binsri exceeds the number of elements, LLVM
suffers an ICE.
Test case:
#include <msa.h>
void test() {
v16i8 v16i8_a = (v16i8) {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};
v16i8 v16i8_r = (v16i8) {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};
v16i8_r = __msa_binsri_b (v16i8_r, v16i8_a, 25)
}
This occurs as due to an assert in APInt::getLowBitsSet() as the number of bits
set is greater than the result.
This requires patch for clang for custom type checking and one in LLVM to
report a fatal error.</pre>
