cmd/compile: use internal/abi types in the compiler
It is tricky to use those types directly, because the layout of those
types in the compiler may not be the same as the layout of those
types in target binary (typically because of 32 vs 64 bit differences).
Instead, translate an internal/abi type into a cmd/compile/internal/types
type, which will then be laid out for the target machine.
Along with the translation, keep track of where all the bits of the
type are so we can reference their locations symbolically instead of
hardcoding them.
