[expand] Fix for PR rtl-optimization/79121 incorrect expansion of extend plus left shift
When generating a shift from an extended value moving from one to two
machine registers, the type of the right shift is for the most
significant word should be determined by the signedness of the inner
type, not the signedness of the result type.
gcc:
PR rtl-optimization/79121
* expr.c (expand_expr_real_2, case LSHIFT_EXPR): Look at the signedness
of the inner type when shifting an extended value.
gcc/testsuite:
* gcc.c-torture/execute/pr79121.c: New test.
