instruction definitions in Alpha.

- List-valued arguments.
Also export makeList() function to Python code blocks,
as this is handy for dealing with flags.

Should enable implementation of split-phase timing loads
with new memory model.
May create slight timing differences under FullCPU, as I
believe we were not handling software prefetches correctly
before when the split MemAcc/Exec model was used. I haven't
looked into this in any detail though.
arch/alpha/isa/decoder.isa:
HwLoadStore format split into separate HwLoad and
HwStore formats.
Copy instructions now fall under MiscPrefetch format.
Mem_write_result is now just write_result in store
conditionals.
arch/alpha/isa/mem.isa:
Split MemAccExecute and LoadStoreExecute templates
into separate templates for loads and stores; now
that memory operands are handled differently from
registers, it's impossible to have a single template
serve both.
Also unified the handling of "regular" prefetches
(loads to r31) and "misc" prefetches (e.g., wh64)
under the new scheme. It looks like SW prefetches
were not handled correctly in FullCPU up til now,
since we generated an execute() method for the outer
instruction but didn't generate a proper method for
MemAcc::execute() (instead getting a default no-op
method for that).
arch/alpha/isa/pal.isa:
Split HwLoadStore into separate HwLoad and HwStore
formats to select proper template (see change to
mem.isa in this changeset).
arch/isa_parser.py:
Stop trying to treat memory operands like register
operands, since we never used them in a uniform way
anyway, and it made it impossible to do split-phase
loads as needed for the new CPU model. Now there's no
more 'op_mem_rd', 'op_nonmem_rd', etc.: 'op_rd' just does
register operands, and the template code is responsible
for formulating the call to the memory system. Right now
the only thing exported by InstObjParams is a new attribute
'mem_acc_size' which gives the memory access size in bits,
though more attributes can be added if needed.
Also moved code in findOperands() method to
OperandDescriptorList.__init__(), which is where it belongs.

-every MIPS32 ISA is represented with some type
of code block.
-any instruction that doesnt have a code block
would be of format WarnUnimpl. Examples of the
ones I am waiting on further info to implement
are the TLB register insts, memory consistency
instructions (ll,sc,etc.) and software debug
insts.

Get rid of "munged name" for operands in C++ code.
That is, "Ra.uq" will now be known in the C++ as "Ra"
rather than "Ra_uq". It wasn't legal to use different
type extensions for the same operand at the same time
anyway, and now it will be easier to refer to explicit
operands in template code if necessary.
