ubsan: epiphany: left shift of negative value
Two places in epiphany_cgen_extract_operand, "value" is a long.
value = ((((value) << (1))) + (pc));
cpu/
* epiphany.cpu (f-simm8, f-simm24): Use multiply rather than
shift left to avoid UB on left shift of negative values.
opcodes/
* epiphany-ibld.c: Regenerate.
