Log:
Get complex numbers working by making LLVM agree with GCC on what a register
is: now we consider complex numbers to be first class values, rather than
keeping them in an alloca like for other aggregates. It is not clear what
effect this has on code quality. While there, handle PAREN_EXPR by just
ignoring it. It's not yet clear to me exactly what this expression implies,
but with these two changes the plugin can compile the Fortran BLAS.

If an ssa name refers to a global (can this happen?), the SSANames map might
need to be updated if the target is altered by changeLLVMConstant.
-An ssa name can be a complex number, causing the plugin to crash. Maybe should
-consider complex numbers to be scalars rather than aggregates. Would this get
-in the way of sroa?

+Code quality
+------------
+
+Check the effect on code speed of having complex numbers be first class
+structures, i.e. values rather than in-memory aggregates.
