Adding AArch64 CurrentEL register
...
CurrentEL is used to determine the current "exception level" in the CPU.
It has four possible results:
0b00 - EL0 - Application
0b01 - EL1 - Rich OS
0b10 - EL2 - Hypervisor
0b11 - EL3 - Firmware

* AArch64: added SIMD instructions (only plain ARMv8-A for now)
...
o added AArch64 regset parsing support in assembler reader, means that "{"
no longer starts comments there (like in the ARM assembler reader)
o added AArch64 indexed SIMD register support and removed old cg hacks
that worked around its absence

somehow committing went wrong, second part of last commit:
...
+ AArch64: support for vX.8b/vX.16b register names
+ support for more than 256 registers in the register dat files
- removed totherregisterset
+ AArch64: use vmov to load immediates if possible
+ AArch64: use eor to clear mm registers
