tci: Fix qemu-alpha on 32 bit hosts (wrong assertions)

Debian busybox-static for alpha has a load address of 0x0000000120000000
which is mapped to 0x0000000020000000 for 32 bit hosts.

qemu-alpha uses the TCG opcodes qemu_ld32, qemu_ld64, qemu_st32 and
qemu_st64 which all raise the assertion (taddr == host_addr).

Remove all assertions of this type because they are either wrong or
unnecessary (when sizeof(tcg_target_ulong) >= sizeof(target_ulong)).
