The float-access functions stfl_*, stfq*, ldfl* and ldfq* are now
unused; remove them. (Accesses to float64 and float32 types can be
made with the ldl/stl/ldq/stq functions, as float64 and float32 are
guaranteed to be typedefs for normal integer types.)

Current documentation is not too clear on the GETPC usage.
In particular, when used outside the top level helper function
it causes unexpected behavior.

We currently have target-endian versions of these operations,
but no easy way to force a specific endianness. This can be
helpful if the target has endian-specific operations, or a mode
that swaps endianness.

The company 'Arm' went through a rebranding some years back
involving a recapitalization from 'ARM' to 'Arm'. As a result
our documentation is a bit inconsistent between the two forms.
It's not worth trying to update everywhere in QEMU, but it's
easy enough to make docs/ consistent.
Note that "ARMv8" and similar architecture names, and
older CPU names like "ARM926" still retain all-caps.

There are no uses of the *_cmmu names other than the bare wrapping
within the *_code inlines. Therefore rename the functions so we
can drop the inlines.
Use abi_ptr instead of target_ulong in preparation for user-only;
the two types are identical for softmmu.

The API of cpu_physical_memory_write_rom() is odd, because it
takes an AddressSpace, unlike all the other cpu_physical_memory_*
access functions. Rename it to address_space_write_rom(), and
bring its API into line with address_space_write().

There's a common pattern in QEMU where a function needs to perform
a data load or store of an N byte integer in a particular endianness.
At the moment this is handled by doing a switch() on the size and
calling the appropriate ld*_p or st*_p function for each size.
Provide a new family of functions ldn_*_p() and stn_*_p() which
take the size as an argument and do the switch() themselves.
