Aurelien Jarno 8df7eef305 target-s390x: wire up DIAG IPL in TCG mode 
DIAG IPL is already implemented for KVM, but not wired from TCG. For
that change the format of the instruction so that we can get R1 and R3
numbers in addition to the function code.

The diag function can change plenty of things, including CC, so we
should enter with a static CC. Also it doesn't set the value of general
register 2 to 0 as in the current code. We also need to exit the CPU
loop after a reset, which means a new PSW.

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.
