memtest: fix/cleanup functional access testing
...
Don't assert that the response packet is marked as a response
since it won't always be so for functional accesses.
Also cleanup code to refer to functional accesses rather
than "probes" (old terminology), and mention in the
DPRINTF which type of access we're doing.

ARM: Support unaligned memory access.
...
Without this flag set, page-crossing requests were not split into two mem
request.
Depending on the alignment bit in the SCTLR, misaligned access could
raise a fault. However it seems unnecessary to implement that.

ARM: Adding a bogus fault that does nothing.
...
This fault can used to flush the pipe, not including the faulting instruction.
The particular case I needed this was for a self-modifying code. It needed to
drain the store queue and force the following instruction to refetch from
icache. DCCMVAC cp15 mcr instruction is modified to raise this fault.

ARM: Use fewer micro-ops for register update loads if possible.
...
Allow some loads that update the base register to use just two micro-ops. three
micro-ops are only used if the destination register matches the offset register
or the PC is the destination regsiter. If the PC is updated it needs to be
the last micro-op otherwise O3 will mispredict.

inUserMode now can take either a threadcontext or a CPSR value directly. If

An inPrivelegedMode function was also implemented which just returns the
opposite of inUserMode.
