As I understand, one of the tricks for converting to SSA form in LLVM
is to make all variable references be loads/stores, then use Mem2Reg
to convert those back to registers.  It seems like using intrinsics
would preclude this and require the front end of the compiler to do
it, which is quite a bit of work.
