Rename target_pointer_width to pointer_width and turn it into an u32

Browse source 
Rename target_pointer_width to pointer_width because it is already
member of the Target struct.

The compiler supports only three valid values for target_pointer_width:
16, 32, 64. Thus it can safely be turned into an int.
This means less allocations and clones as well as easier handling of the type.
