Register definitions for treating the 4 ARM64 flags separately
As with dataflow analysis on other architectures, each flag should be treated
as a distinct unit. Following changes, made as part of this commit, achieve
this:
- n, z, c and v have been added as individual register definitions in dyn_regs
with their baseIDs indicating their positions in the pstate register. The
conversions from Dyninst to ROSE registers for these new additions are also
defined.
- The 'nzcv' enum value in ARMv8PstateFields (for use in ARM semantics) is
split into 4 different values, one for each flag. Each of these is also added
to the register dictionary for ARMv8 in Registers.C.
