Make "end" field in feature specs required again.
Newer gdbservers may be talking to older gdbs,
and older gdbs will flag a missing "end" as an error.
So just make "end" required again, and for compatibility
change the default field type to "bool".
gdb/ChangeLog:
2016-10-06 Doug Evans <dje@google.com>
* features/aarch64-core.xml (cpsr_flags): Elide "type" and specify
"end" in all fields.
* features/aarch64.c: Regenerate.
* features/i386/32bit-mpx.xml (_bndcfgu): Specify type of "preserved"
and "enabled" fields. Correct size of "enabled" field.
* features/i386/64bit-mpx.xml (_bndcfgu): Specify type of "preserved"
and "enabled" fields.
* features/i386/i386-avx-mpx-linux.c: Regenerate.
* features/i386/i386-avx-mpx.c: Regenerate.
* features/i386/i386-avx512-linux.c: Regenerate.
* features/i386/i386-avx512.c: Regenerate.
* features/i386/i386-mpx-linux.c: Regenerate.
* features/i386/i386-mpx.c: Regenerate.
* features/arc-arcompact.c: Regenerate.
* features/arc-v2.c: Regenerate.
* xml-tdesc.c (tdesc_start_field): Require "end" spec. Single bit
fields default to "bool" type.
