Undo class_linker.cc workaround for out of registers bug.
Bug: http://b/30419309
Test: Built x86_64/x86 targets successfully with latest toolchain.
This change re-enables optimization for a function in class_linker.cc
that previously exposed an internal compiler error in Clang. Now that
the bug has been fixed, we can remove the workaround.
