base: Add compiler macros to add deprecation warnings
Gcc and clang both provide an attribute that can be used to flag a function as deprecated at compile time. This changeset adds a gem5 compiler macro for that compiler feature. The macro can be used to indicate that a legacy API within gem5 has been deprecated and provide a graceful migration to the new API.
