Change get_objfile_arch to a method on objfile
This changes get_objfile_arch to be a new inline method,
objfile::arch.
To my surprise, this function came up while profiling DWARF psymbol
reading. Making this change improved performance from 1.986 seconds
to 1.869 seconds. Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.
