This patch finishes the job of removing insn_flags and moves the logic
over to using the new data structures. I've added a new boolean
variable to detect when we have ARMv7ve-like capabilities and thus
have 64-bit atomic operations since that would be a complex query and
expensive to do in full. It might be better to add a specific bit to
the ISA data structures to indicate this capability directly.
* arm-protos.h (insn_flags): Delete declaration.
(arm_arch7ve): Declare.
* arm.c (insn_flags): Delete.
(arm_arch7ve): New variable.
(arm_selected_cpu): Delete.
(arm_option_check_internal): Use new ISA bitmap.
(arm_option_override_internal): Likewise.
(arm_configure_build_target): Declare arm_selected_cpu locally.
(arm_option_override): Use new ISA bitmap. Initialize arm_arch7ve.
Rearrange variable intialization by general function.
* arm.h (TARGET_HAVE_LPAE): Use arm_arch7ve.
