tcg: Add qemu_ld_st_i32/64

Step two in the transition, adding the new ldst opcodes. Keep the old
opcodes around until all backends support the new opcodes.

exec: Add both big- and little-endian memory helpers

Step three in the transition: helpers not tied to the target
"default" endianness. To be used when the guest uses a memory
operation with non-default endianness.

tcg: Add tcg-be-null.h

This is a no-op backend data implementation, for those targets that
are not currently using the load/store optimization path.

This is prepatory to always requiring these functions in all backends.

tcg: Add tcg-be-ldst.h

Move TCGLabelQemuLdst and related stuff out of tcg.h.

tcg: Put target helper data into an array.

One call inside of a loop to tcg_register_helper instead of hundreds
of sequential calls.

Presumably more icache and branch prediction friendly; resulting binary
size mostly unchanged on x86_64, as we're trading 32-bit rip-relative...

tcg: Add tcg-runtime.c helpers to all_helpers

For the few targets that actually use these, we'd not report
them symbolicly in the tcg opcode logs.

tcg: Merge tcg_register_helper into tcg_context_init

Eliminates the repeated checks for having created
the s->helpers hash table.

tcg-aarch64: Update to helper_ret_*_mmu routines

A minimal update to use the new helpers with the return address argument.

tcg: Move helper registration into tcg_context_init

No longer needs to be done on a per-target basis.
