x86: x86-64 ptrace debugreg cleanup
This cleans up the 64-bit ptrace code to separate the guts of the
debug register access from the implementation of PTRACE_PEEKUSR and
PTRACE_POKEUSR. The new functions ptrace_[gs]et_debugreg are made
global so that the ia32 code can later be changed to call them too.
