  target/nios2: Replace DISAS_TB_JUMP with DISAS_NORETURN

The only semantic of DISAS_TB_JUMP is that we've done goto_tb,
which is the same as DISAS_NORETURN -- we've exited the tb.

Direct assignments to env during translation do not work.

As it happens, the only way we can get here is if env->pc

we execute anywhere on the page.

  tcg: Use correct trap number for page faults on *BSD systems

The trap number for a page fault on BSD systems is T_PAGEFLT
not 0xe -- 0xe is used by Linux and represents the intel hardware
trap vector. The BSD kernels, however, translate this to T_PAGEFLT
in their Xpage, Xtrap0e, Xtrap14, etc fault handlers. This is true
for i386 and x86_64, though the name of the trap hanlder can very
on the flavor of BSD. As far as I can tell, Linux doesn't provide
a define for this value. Invent a new one (PAGE_FAULT_TRAP) and
use it instead to avoid uglier ifdefs.

  tcg: Add flags argument to bswap opcodes

This will eventually simplify front-end usage, and will allow
backends to unset TCG_TARGET_HAS_MEMORY_BSWAP without loss of
optimization.

The argument is added during expansion, not currently exposed to the
front end translators.  The backends currently only support a flags
value of either TCG_BSWAP_IZ, or (TCG_BSWAP_IZ | TCG_BSWAP_OZ),
since they all require zero top bytes and leave them that way.
At the existing call sites we pass in (TCG_BSWAP_IZ | TCG_BSWAP_OZ),
except for the flags-ignored cases of a 32-bit swap of a 32-bit
value and or a 64-bit swap of a 64-bit value, where we pass 0.

For the sf version, we are performing two 32-bit bswaps
in either half of the register.  This is equivalent to
performing one 64-bit bswap followed by a rotate.

For the non-sf version, we can remove TCG_BSWAP_IZ
and the preceding zero-extension.

  target/arm: Improve vector REV

We can eliminate the requirement for a zero-extended output,
because the following store will ignore any garbage high bits.

  target/mips: Fix gen_mxu_s32ldd_s32lddr

There were two bugs here: (1) the required endianness was
not present in the MemOp, and (2) we were not providing a
zero-extended input to the bswap as semantics required.

The best fix is to fold the bswap into the memory operation,
producing the desired result directly.

used for optimizing bswap for signed loads and for stores, do not
pretend to have these memory ops in the backend.

The memory bswap support in the aarch64 backend merely dates from
a time when it was required.  There is nothing special about the
backend support that could not have been provided by the middle-end
even prior to the introduction of the bswap flags.

  tcg/riscv: Remove MO_BSWAP handling

TCG_TARGET_HAS_MEMORY_BSWAP is already unset for this backend,
which means that MO_BSWAP be handled by the middle-end and
will never be seen by the backend.  Thus the indexes used with
qemu_{ld,st}_helpers will always be zero.

Tidy the comments and asserts in tcg_out_qemu_{ld,st}_direct.
It is not that we do not handle bswap "yet", but never will.
