"exec/exec-all.h" is now fully empty, let's remove it.
Mechanical change running:
$ sed -i '/exec\/exec-all.h/d' $(git grep -wl exec/exec-all.h)

When update_pagemask was split from helper_mtc0_pagemask,
we failed to actually write to the new parameter but continue
to write to env->CP0_PageMask. Thus the use within
page_table_walk_refill modifies cpu state and not the local
variable as expected.
Simplify by renaming to compute_pagemask and returning the
value directly. No need for either env or pointer return.

Revert ee3863b9d4 and a08d60bc6c. The logic behind changing
the system page size because of what the Loongson kernel "prefers"
is flawed.
In the Loongson-2E manual, section 5.5, it is clear that the cpu
supports a 4k page size (along with many others). Similarly for
the Loongson-3 series CPUs, the 4k page size is mentioned in the
section 7.7 (PageMask Register). Therefore we must continue to
support a 4k page size.

Headers in include/sysemu/ are not only related to system
*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.
Files renamed manually then mechanical change using sed tool.
