[GCC, ARM] Enable armv8.5-a and add +sb and +predres for previous ARMv8-a in ARM
This patch adds -march=armv8.5-a to the Arm backend.
Armv8.5-A also adds two new security features:
- Speculation Barrier instruction
- Execution and Data Prediction Restriction Instructions
These are made optional to all older Armv8-A versions. Thus we are adding two
new options "+sb" and "+predres" to all older Armv8-A. These are passed on to
the assembler and have no code generation effects and have already gone in the
trunk of binutils.
