replace if-s in AArch64_AM_decodeAdvSIMDModImmType10 with lookup table (#552) * 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
