While we still require the LONG DISPLACEMENT facility, defaults
have moved on since then.  Don't override the system compiler,
whose default may be set to z9-109 or later.

There are a variety of common cases for which we can use carry tricks to
avoid a conditional branch.  On very new hardware, use LOAD ON CONDITION
instead of a conditional branch.

Commit af3cbfbe hoisted some "common"
loads of the temporary type, forgetting that the types could differ
during truncating moves.  This affects the correctness of the memory
offset on big-endian hosts.

  exec-all.h: Use stl_le_p instead of stl_p patching x86
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

We got the wrong version of stl_p, the one that bswaps as appropriate
for the target.  Since x86 is always little-endian, the "_le_" routine
will resolve to what we want.

Commit e586822a broke the bsd-user build when it removed the
CONFIG_UNAME_RELEASE define but forgot to remove the use of it
in bsd-user. Fix this in the simplest possible way (bsd-user
doesn't make any use at all of the qemu_uname_release variable
except to allow it to be pointlessly set by the user, so this
is all we need to do.)

There was some modulo logic to ensure that Microblaze always booted into
physical RAM regardless of the elf entry. Removed it, as QEMU should fail
gracefully when given a bad elf, rather than attempt to run it.

The TCSR register has only 11 valid bits. This is now used by the
linux kernel to auto-detect endianness, and causes Linux 3.15-rc1
and later to hang when run under qemu-microblaze. Mask valid bits
before writing the register to solve the problem.

The INDEX_op_call case has just been obsoleted; the mov and movi
cases have not been reachable for years.  Attempt to document this
both in each tcg_out_op switch, and via TCG_OPF_NOT_PRESENT.

Because of the TCG_OPF_NOT_PRESENT change, this must be done for
all targets in a single commit.

The move opcodes are special in that their constraints must cover
all available registers.  So instead of checking the constraints,
just use the available registers.

Avoid allocating a tcg temporary to hold the constant address,
and instead place it directly into the op_call arguments.

At the same time, convert to the newly introduced tcg_out_call
backend function, rather than invoking tcg_out_op for the call.

Using a 16-byte aligned structure achieves best results, both for code
cleanliness and compiled code size.  However, this means that we can't
use the trick of encoding the slot number into the low 2 bits.

Thankfully, we only ever use slot2, so make that explicit in the names
of the relocation functions, and drop the code for other slots.
