* config/tc-v850.c (md_assemble): Allow signed values for
V850E_IMMEDIATE.
* gas/v850/basic.exp: Allow for variations in reloc names.
* gas/v850/split-lo16.d: Likewise.
* gas/v850/v850e1.s: Add more tests of the PREPARE insn.
* gas/v850/v850e1.d: Update expected disassembly.
* v850-dis.c (get_operand_value): Sign extend V850E_IMMEDIATE
values.
* v850-opc.c (IMM16LO): Add V850_OPERAND_SIGNED attribute.
