Daco Harkes 4081235ac5 [vm] Support unboxed indices in indexed load and store 
Use unboxed indices in FFI loads, eliminating extra boxing and a shift for 1-byte loads.
Speeds up Pointer<Int8,Int64,etc> loads/stores by 20-25% in AOT on x64.

This does not use the unboxed indices in TypedData yet, using unboxed in TypedData without making the bounds checks unboxed makes it slower instead of faster.
