Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h. This
minimizes the files that must be rebuilt when changing the macros
for file N.

Per Alex Graf's suggestion, the recently added case to gen_conditional_store
for stqcx should use an additional temporary when accessing the second
doubleword. This avoids the mutation of the EA argument to the function,
which is counter intuitive.

Some Alitvec instructions introduced in Power ISA Version 2.07 use bit 31
(aka the "Rc" bit) as an opcode but also use bit 21 as an actual Rc
bit. QEMU for PowerPC typically uses bits 0-5 and 21-30 for opcodes.
This patch introduces a generator macro that injects an auxiliary handler
which decodes both bits 21 and 31 and invokes one of four standard
handlers. Since the instructions are not, in general, from the same version
of the ISA, two sets of PPC_*/PPC2_* flags are supported.
This patch also introduces a macro to insert two entries into the opcode
table -- one for bit 21 equal to 0 and one for bit 21 equal to 1.
