Introduce gdb_disassembly_flags
For some reason I ended up staring at some of the "int flags" in btrace-related code, and I got confused because I had no clue what the flags where supposed to indicate. Fix that by using enum_flags, so that: #1 - it's clear from the type what the flags are about, and #2 - the compiler can catch mismatching mistakes gdb/ChangeLog: 2017-09-04 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (print_disassembly, disassemble_current_function) (disassemble_command): Use gdb_disassembly_flags instead of bare int. * disasm.c (gdb_pretty_print_disassembler::pretty_print_insn) (dump_insns, do_mixed_source_and_assembly_deprecated) (do_mixed_source_and_assembly, do_assembly_only, gdb_disassembly): Use gdb_disassembly_flags instead of bare int. * disasm.h (DISASSEMBLY_SOURCE_DEPRECATED, DISASSEMBLY_RAW_INSN) (DISASSEMBLY_OMIT_FNAME, DISASSEMBLY_FILENAME) (DISASSEMBLY_OMIT_PC, DISASSEMBLY_SOURCE) (DISASSEMBLY_SPECULATIVE): No longer macros.
