Introduce a new plugin_mem_cb op to hold the address temp
and meminfo computed by tcg-op-ldst.c. Because this now
has its own opcode, we no longer need PLUGIN_GEN_FROM_MEM.

For normal helpers, read the function pointer from the
structure earlier. For plugins, this will allow the

The CPUBreakpoint and CPUWatchpoint structures are declared

We usually check target endianess before swapping values,
so target_words_bigendian() declaration makes sense in
"exec/tswap.h" with the target swapping helpers.
Remove "hw/core/cpu.h" when it was only included to get

Since commit 139c1837db ("meson: rename included C source files
to .c.inc"), QEMU standard procedure for included C files is to
use *.c.inc.
Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:
If you do use template header files they should be named with
the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
being included for expansion.
Therefore rename "exec/helper-head.h" as "exec/helper-head.h.inc".
