cpu: Removed unnecessary file reg_class_impl.hh

Previously, reg_class_impl.hh was added in order to prevent a cyclic
dependency between it and the_isa.hh (See
http://reviews.gem5.org/r/3754). It was determined that this was not
necessary. The two files had almost entirely the same includes, and the
current test-suite including multiple gcc and clang compilers on both
MacOS and Linux successfully built the library with all functionality
moved into the reg_class.hh file.
