[PATCH v2 00/28] cputlb: Remove support for MMU_MODE*_SUFFIX |

This is part of a project to raise the limit on NB_MMU_MODES.
One of those is in cpu_ldst.h, in support of MMU_MODE*_SUFFIX.
While this could be extended, it's not the best interface for
such things. Better is a single interface that allows a variable
mmu_idx. The best exemplars of that is the usage in target/mips
and target/ppc.
In the process, I tried to clean up the implementation of these
functions for softmmu and user-only.
Aleksander asked about code size changes. They vary between
a minor size increase (e.g. for qemu-system-alpha, where there
are in fact no uses of the functions, which are now present as
out-of-line functions rather than eliminated inline functions),
to a minor size decrease (e.g. -79k/-1.6% for qemu-system-i386).
See below for details.
Changes for v2:
* Significantly revised docs/devel/loads-stores.rst.
* m68k and s390x dropped #defines and use *_mmuidx_ra directly.
