FreeBSD head, LLVM 11.0.0-rc2-91-g6e042866c30, powerpc64le (builds on
powerpc64)

Test case:
struct c {
  unsigned char b;
  char d;
  char blue;
};
double e;
c f(c g) {
  c a;
  a.b = g.b * e;
  return a;
}

Build with:
/usr/bin/c++ -cc1 -triple powerpc64-unknown-freebsd13.0 -emit-obj -O>
0 -emit-obj -O1 OCOLTBL-26eb53.cpp

Result:
Assertion failed: (isSimple() && "Expected a SimpleValueType!"), function
getSimpleVT, file
/usr/src/contrib/llvm-project/llvm/include/llvm/CodeGen/ValueTypes.h, line 261.
