Other than arrays and complex procvardefs, all aggregates are currently
handled as opaque arrays of bytes
o special case: s80real (x87 extended type) is encoded as "array[0..9] of
byte" inside arrays, because when using the llvm type describing
"extended" llvm will handle it in an ABI-compliant way (allocating e.g.
16 bytes for it on Darwin and x86-64 platforms). Loading/storing them
always happens using instructions that only read/write 10 bytes, so
we only have to take care to convert them to the actual extended type
when indexing arrays/subscripting records (when records are no longer
handled in an opaque way)
