Changed size of `AVX2`-gather memory operands to match `AVX512` 
The operand-size is now the size of a single element instead of the total size (like it already is for the `AVX512` gather/scatter instructions)

Joel Höner fa12ccb64b Switch to length aware string 2017-12-01 20:40:56 +01:00
flobernd 930c4df970
Removed `ZydisDecodedInstruction.instrPointer` 
The instruction-pointer was always pointing to the next instruction (which is inconsistent for branch instructions). We can't always tell IF an instruction is going to branch (for the conditional ones), so we decided to completely remove it.

You can always manually combine `instrAddress` and `length` to calculate this value.
