readability and also fixes some minor issues.
S/390: Split disassembler routine into smaller functions
S/390: Fix disassembler's treatment of signed/unsigned operands
S/390: Fix off-by-one error in disassembler initialization
S/390: Simplify opcode search loop in disassembler
S/390: Drop function pointer dereferences in disassembler
S/390: Various minor simplifications in disassembler
Currently the disassembler for s390 (by default) assumes that a 31-bit
binary was compiled in "ESA" mode -- and then only disassembles a
limited opcode set. The change upgrades the default to the full "zarch"
opcode set even for 31-bit binaries.
