Remove objfile_type
This removes objfile_type, in favor of always using the per-arch builtins. Reviewed-By: Simon Marchi <simon.marchi@efficios.com>

- The upshot is:

- representation.
- - gdb's `struct value' objects should always hold values in
- target form.
- - gdb's CORE_ADDR values are addresses in the unified virtual
- address space that the assembler and linker work with. Thus,
- since target_read_memory takes a CORE_ADDR as an argument, it
- can access any memory on the target, even if the processor has
- separate code and data address spaces.
-
- In this context, objfile_type->builtin_core_addr is a bit odd:
- it's a target type for a value the target will never see. It's
- only used to hold the values of (typeless) linker symbols, which
- are indeed in the unified virtual address space. */
