We have fetched and locked the logfile in translator_loop.
Pass the filepointer down to the disas_log hook so that it
need not be fetched and locked again.

Marc-André Lureau e03b56863d Replace config-time define HOST_WORDS_BIGENDIAN
Replace a config-time define with a compile time condition
define (compatible with clang and gcc) that must be declared prior to
its usage. This avoids having a global configure time define, but also
prevents from bad usage, if the config header wasn't included before.

This can help to make some code independent from qemu too.

gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

Nico Boehr 2092fdd97c s390x: sck: load into a temporary not into in1
We previously loaded into in1, but in1 is not filled during
disassembly and hence always zero. This leads to an assertion failure:

  qemu-system-s390x: /home/nrb/qemu/include/tcg/tcg.h:654: temp_idx:
  Assertion `n >= 0 && n < tcg_ctx->nb_temps' failed.`

Instead, use in2_la2_m64a to load from storage into in2 and pass that to
the helper, which matches what we already do for SCKC.

This fixes the SCK test I sent here under TCG:

Ilya Leoshkevich 6da170beda target/s390x: Fix shifting 32-bit values for more than 31 bits
According to PoP, both 32- and 64-bit shifts use lowest 6 address
bits. The current code special-cases 32-bit shifts to use only 5 bits,
which is not correct. For example, shifting by 32 bits currently
preserves the initial value, however, it's supposed zero it out
instead.

Fix by merging sh32 and sh64 and adapting CC calculation to shift
values greater than 31.

Ilya Leoshkevich 57556b28af target/s390x: Fix SRDA CC calculation
SRDA uses r1_D32 for binding the first operand and s64 for setting CC.
cout_s64() relies on o->out being the shift result, however,
wout_r1_D32() clobbers it.

Fix by using a temporary.

We use INDEX_op_insn_start to make the start of instruction boundaries.
If we don't do it in the .insn_start hook things get confused especially
now plugins want to use that marking to identify the start of instructions
and will bomb out if it sees instrumented ops before the first instruction
boundary.
