Instead of deciding at runtime whether to read from casetest.value or caseValue_datum, split EEOP_CASE_TESTVAL into two opcodes and make the decision during expression compilation. Similarly for EEOP_DOMAIN_TESTVAL. This actually results in net less code, mainly because llvmjit_expr.c's code for handling these opcodes gets shorter. The performance gain is doubtless negligible, but this seems worth changing anyway on grounds of simplicity and understandability.
