Paolo Bonzini 63c915526d cpu: move exec-all.h inclusion out of cpu.h
exec-all.h contains TCG-specific definitions.  It is not needed outside
TCG-specific files such as translate.c, exec.c or *helper.c.

One generic function had snuck into include/exec/exec-all.h; move it to
include/qom/cpu.h.

Aurelien Jarno 92f2b4e71e target-s390x: fix CONVERT TO BINARY (CVD, CVDY)
current_number being shift left by more than 32 bits, we can't use a
simple int. Similarly use an int64_t type for the input binary value,
to not get the -2^31 case wrong. Finally don't initialize shift to 4,
it's already done in the for loop.

Aurelien Jarno d30107814c target-s390x: optimize (negative-) abs computation
Now that movcond exists, it's easy to write (negative-) absolute value
using TCG code instead of an helper.

Richard Henderson 2ef6175aa7 tcg: Invert the inclusion of helper.h
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.

Gabriel Kerneis d49b8e0b29 s390x: use CONFIG_INT128 to detect __uint128_t
Target s390x uses ad-hoc macro magic to guess if the compiler
supports the GCC extension __uint128_t.  This patch uses the
the dedicated macro CONFIG_INT128 defined by configure instead.

This fixes compilation with the CIL source code analyzer, which
uses GCC as a preprocessor but does not support __uint128_t.

Richard Henderson 4e4bb43899 target-s390: Convert ADD LOGICAL CARRY and SUBTRACT LOGICAL BORROW
I'm resonably certain that the carry/borrow-out condition for both
helpers was incorrect, failing to take into account the carry-in.
Adding the new CC_OP codes also allows removing the awkward interface
we used for the slb helpers.

Richard Henderson 1ac5889f48 target-s390: Convert 64-bit MULTIPLY LOGICAL
Use a new "retxl" member of CPUS290XState to return the "eXtra Low" part
of a 128-bit value.  That said, this will get used when two independent
values need returning (e.g. quotient+remainder) as well.

At the same time, shuffle the elements of CPUS390XState to get this new
space from existing padding in the structure.
