b939b8e42a exec: Rename target_words_bigendian() -> target_big_endian()
In commit 98ed8ecfc9 ("exec: introduce target_words_bigendian()
helper") target_words_bigendian() was matching the definition it
was depending on (TARGET_WORDS_BIGENDIAN). Later in commit
ee3eb3a7ce ("Replace TARGET_WORDS_BIGENDIAN") the definition was
renamed as TARGET_BIG_ENDIAN but we didn't update the helper.
Do it now mechanically using:

  $ sed -i -e s/target_words_bigendian/target_big_endian/g \
        $(git grep -wl target_words_bigendian)

663310b05c exec/tswap: implement {ld,st}.*_p as functions instead of macros
Defining functions allows to use them from common code, by not depending
on TARGET_BIG_ENDIAN.
Remove previous macros from exec/cpu-all.h.
By moving them out of cpu-all.h, we'll be able to break dependency on
cpu.h for memory related functions coming in next commits.

425082612c exec: Declare target_words_bigendian() in 'exec/tswap.h'
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
the target_words_bigendian() declaration.

7d7a21ba69 exec: Rename NEED_CPU_H -> COMPILING_PER_TARGET
'NEED_CPU_H' guard target-specific code; it is defined by meson
altogether with the 'CONFIG_TARGET' definition. Rename NEED_CPU_H
as COMPILING_PER_TARGET to clarify its meaning.

Mechanical change running:

 $ sed -i s/NEED_CPU_H/COMPILING_PER_TARGET/g $(git grep -l NEED_CPU_H)

then manually add a /* COMPILING_PER_TARGET */ comment
after the '#endif' when the block is large.

24be3369ad include/exec: Provide the tswap() functions for target independent code, too
In some cases of target independent code, it would be useful to have access
to the functions that swap endianess in case it differs between guest and
host. Thus re-implement the tswapXX() functions in a new header that can be
included separately. The check whether the swapping is needed continues to
be done at compile-time for target specific code, while it is done at
run-time in target-independent code.
