Implement byte swizzle operations

Add Swizzle() intrinsics for Byte16, Byte8, and Byte4, and add Byte4 constructors and assignment operators. Also move LLVM-specific implementations to the generic Reactor.cpp source file. On x86 these all translate to a pshufb instruction, which is very efficient.

Note that this is a bitwise cast. Unlike C++'s ```reinterpret_cast<>```, it does not allow casting between different sized types. Think of it as storing the value in memory and then loading from that same address into the casted type.
An important exception is that 16-, 8-, and 4-byte vectors can be cast to other vectors of one of these sizes. Casting to a longer vector leaves the upper contents undefined.
