Add in exec_context.hh, which is a file for documentation purposes only. It describes the ExecContext interface that the ISA uses to access CPU state. Also #ifdef Erik's old copy code from the decoder so ExecContext doesn't need his two specific copy functions.
src/arch/alpha/isa/decoder.isa:
Surround Erik's old copy code with #ifdefs. This way the copy functions don't need to be included in the ExecContext (until somebody decides to add them back in).
