When compiling with DEBUG_TCGV enabled, make the TCGv_ptr type distinct
from TCGv_i32/TCGv_i64. This means that using an i32 or i64 TCG op to
manipulate a TCGv_ptr will always be detected at compile time, rather
than only if compiling on a host system with the other word size.

NB: the tcg_add_ptr and tcg_sub_ptr macros have been removed as they
were not used anywhere.

The prototypes for the ld/st functions on a 64 bit host declared
the address parameter as a TCGv_i64 rather than a TCGv_ptr. This
worked OK (since the two are aliases), but needs to be fixed to
allow extension of TCG type debugging to i64/i32/ptr mismatches.

The cksm instruction was implemented incorrectly, rendering UDP and TCP
checksum calculation wrong, making an emulated s390x Linux guest break
in most networking operations.

This patch fixes odd end checksum calculation, takes the input register
as input for the checksum and optimizes the overflow pieces by a bit.

The disas_a5() function provided a TCG tmp variable which was populated
by the respective opcode implementations, but freed at the end of the
function in generic code.

That makes it really hard for code review, so let's move the freeing
to the same scope as the actual allocation.

When compiling qemu with kvm support on BookE PPC machines, I get

  /tmp/qemu/target-ppc/kvm.c: In function 'kvm_arch_get_registers':
  /tmp/qemu/target-ppc/kvm.c:188: error: unused variable 'sregs'

This is due to overly ambitious #ifdef'ery introduced in 90dc88.
Fix it by keeping code that doesn't depend on new headers alive
for the compiler, but never executed due to failing capability
checks.
