[PATCH 0/2] target/ppc: Implement Dynamic Execution Control Registers

[Nicholas Miehlbradt]

Implements the Dynamic Execution Control Register (DEXCR) and the
Hypervisor Dynamic Execution Control Register (HDEXCR) in TCG as 
defined in Power ISA 3.1B. Only aspects 5 (Non-privileged hash instruction 
enable) and 6 (Privileged hash instruction enable) have architectural 
effects. Other aspects can be manipulated but have no effect on execution.

Adds checks to these registers in the hashst and hashchk instructions so
that they are executed as nops when not enabled.
