(GDB/MI Miscellaneous Commands): Change (@value{GDBP})->(gdb),
since the MI prompt is hard-wired into the code.
(GDB/MI Simple Examples): Use @subheading for "A Bad Command".
(GDB/MI Data Manipulation): Remove description of unimplemented
display related commands as variable objects perform this function
and are superior: -display-delete, -display-disable,
-display-enable, -display-insert and -display-list. Move
-environment-cd, -environment-directory, -environment-path
and -environment-pwd to "Program Context".
(GDB/MI Program Control): Rename to "Program Execution". Move
-exec-arguments -exec-abort to...

* config/tc-i386.c (cpu_arch_tune_set): New.
(cpu_arch_isa): Likewise.
(i386_align_code): Use xchg %ax,%ax for 2 byte nop. Optimize
nops with short or long nop sequences based on -march=/.arch
and -mtune=.
(set_cpu_arch): Set cpu_arch_isa. If cpu_arch_tune_set is 0,
set cpu_arch_tune and cpu_arch_tune_flags.
(md_parse_option): For -march=, set cpu_arch_isa and set
cpu_arch_tune and cpu_arch_tune_flags if cpu_arch_tune_set is
0. Set cpu_arch_tune_set to 1 for -mtune=.
(i386_target_format): Don't set cpu_arch_tune.
