* replace if-s in AArch64_AM_decodeAdvSIMDModImmType10 with lookup table

Lookup table is much faster than bunch of if-s. If you don't like lookup tables, I have another proposal. See http://goo.gl/RjW1lr and compare generated machine code

* Smaller lookup table and shifting and bit mask used

* Update AArch64AddressingModes.h
