Sets a value in memory in a dynamic way at run-time. Uses the type data. This is the same as makeSetValue, except that makeSetValue is done at compile-time and generates the needed code then, whereas this function picks the right code at run-time. Note that setValue and getValue only do *aligned* writes and reads! Note that ccall uses JS types as for defining types, while setValue and getValue need LLVM types ('i8', 'i32') - this is a lower-level operation
